A Beginner’s Guide to Finding Free Food and Medicine
Aotearoa New Zealand’s landscape offers an incredible diversity of edible and medicinal plants—from native taonga like kawakawa to introduced “weeds” like dandelion and plantain. This guide will help you safely identify and use these plants, connecting you to the land while building practical skills.
The Golden Rule: If you’re not 100% certain of a plant’s identity, don’t use it. Misidentification can range from unpleasant to deadly.
Why Forage in New Zealand?
It’s Free and Accessible Many powerful medicinal and nutritious plants grow as “weeds” in parks, gardens, and pathways. You don’t need money or special equipment to start—just knowledge and respect.
It Connects You to Place Foraging teaches you to see your environment differently. That “weed” on your street corner becomes medicine for bee stings. The “pest” in your lawn becomes a nutrient-dense green for your salad.
It’s Sustainable When done responsibly, foraging is one of the most sustainable ways to source herbs and food. You’re working with what nature provides, not demanding what industrial agriculture must produce.
It Builds Resilience Knowing which plants around you are edible and medicinal creates food security and healthcare independence. These skills have value in any era.
Cultural Context and Scope
This guide addresses foraging in Aotearoa New Zealand from a Western herbalism perspective.
Rongoā Māori and Traditional Gathering:
Rongoā Māori has its own traditional gathering practices, protocols (kawa), spiritual frameworks (karakia), and deep cultural relationships with native plants. Foraging in Aotearoa requires understanding and respecting these existing Indigenous practices and connections to whenua (land).
CRITICAL: NZ Native Plant Protocols New Zealand native plants have profound cultural significance:
- Kawakawa, mānuka, horopito, harakeke, karamu and many others are taonga (treasures)
- Traditional protocols (kawa) exist for gathering these plants
- Spiritual practices (karakia) accompany traditional gathering
- DO NOT harvest native plants without:
- Understanding their cultural significance – Consulting with rongoā practitioners – Understanding appropriate tikanga (protocols)
- STRONGLY RECOMMEND: Cultivation over wild harvesting for natives
- Respect rāhui (customary prohibitions) on specific areas/species
- Many areas have iwi/hapū management plans governing plant gathering
This Guide Focuses On:
Western foraging practices for introduced/naturalised medicinal herbs in Aotearoa New Zealand, NZ-specific regulations (DOC, council bylaws), conservation considerations, and identification of common introduced species. When native plants are mentioned, it is for identification/awareness purposes only—harvest guidance applies to introduced species.
Why NZ-Specific Foraging Knowledge Matters:
Unique flora (natives + introduced), specific regulations (DOC land, council bylaws), biosecurity considerations (pest plants), Tiriti o Waitangi obligations (respecting mana whenua), conservation status awareness.
The Non-Negotiable Safety Rules
Rule 1: 100% Certainty Before Use
Never consume a plant unless you’re absolutely certain of its identity. “Pretty sure” isn’t certain enough. One dangerous plant in New Zealand (and it does grow here) is poison hemlock (Conium maculatum)—it looks similar to harmless plants but causes respiratory paralysis and death.
How to Be Certain:
- Use multiple identification sources (books, apps, websites)
- Learn one plant thoroughly before moving to the next
- When starting, forage with experienced people
- Take clear photos from multiple angles
- Cross-reference distinctive features
Rule 2: Harvest Only From Clean Locations
Never harvest from:
- Roadsides (within 10 metres): Heavy metals from vehicle exhaust, lead from historical petrol, spray drift from weed control
- Sprayed areas: Council parks, sports fields, and many public reserves are regularly sprayed with herbicides
- Industrial sites: Contamination from historical industrial use can persist in soil for decades
- Dog exercise areas: Risk of parasites and bacteria from faeces
- Downstream from farms: Agricultural runoff contains pesticides, herbicides, and animal waste
Safe harvest locations:
- Your own unsprayed garden
- Friends’/family’s gardens (with permission)
- Known unsprayed areas (verify with council or landowner)
- Clean, unpolluted native bush areas (with appropriate permissions)
Why this matters: Plants absorb what’s in the soil and air. Contamination is invisible—you can’t see herbicides, heavy metals, or pathogens.
Rule 3: Understand DOC Land Regulations
Can you forage on DOC conservation land?
It’s complicated. DOC land includes national parks, conservation areas, and various protected zones covering about one-third of New Zealand.
General Guidelines:
- Small-scale personal harvest of common introduced plants (like dandelion from a carpark) is generally tolerated in unrestricted areas
- National parks and reserves often have stricter rules—check with local DOC office first
- Commercial harvest requires permits and concessions
- Threatened or rare plants should never be harvested regardless of location
- Native plants may have special protections, especially in conservation areas
Best practice: Contact your local DOC office before foraging on any conservation land. They can tell you what’s allowed in specific areas.
More info: doc.govt.nz
Private land: Always get landowner permission. Foraging without permission is trespassing.
Council land: Most councils spray for weeds. Assume sprayed unless confirmed otherwise. Contact your council for spray schedules.
Rule 4: Harvest Sustainably
The 1/10th Rule (Actually 1/20th):
Never take more than 5-10% of any plant population in a given area.
Why this matters:
- Plants need population density to reproduce successfully
- Wildlife depends on these plants for food
- Overharvesting can eliminate local populations
- Some plants take years to recover from damage
In practice:
- If you see 20 plantain plants, harvest from 1-2 plants maximum
- Spread harvesting across a wide area
- For abundant introduced “weeds,” you have more flexibility
- For native plants (especially kawakawa), be extra conservative—take a few leaves from multiple plants, never strip one plant
Rule 5: Start Small With New Plants
Even with correct identification, try only a small amount first.
Why: Individual allergies exist. Some people react to plants that are generally safe for others.
The protocol:
- Make weak tea or eat a few leaves
- Wait 24 hours
- Watch for reactions: rash, digestive upset, headache
- If all is well, gradually increase amount
- One new plant at a time
Eight Beginner-Friendly Plants for Aotearoa New Zealand
These plants are widespread, relatively easy to identify, and have practical uses. Start with these to build confidence.
1. Plantain (Plantago major and P. lanceolata)


Identification:
- Broadleaf plantain: Broad, oval leaves with distinctive parallel veins running from base to tip (unusual for a non-grass plant)
- Ribwort plantain: Narrow, lance-shaped leaves with same parallel veining
- Both form basal rosettes (leaves grow from ground level)
- Flower spikes rise from centre
- Thrives in compacted soil—lawns, pathways, parking lots
Where to Find: Everywhere—it’s probably in your yard right now
Traditional Use: First aid plant in European and indigenous American herbalism for wounds, stings, bites
Current Research: Laboratory studies confirm antimicrobial and anti-inflammatory activity from compounds called aucubin and allantoin
Why This Matters:
Plantain is your free first-aid kit. Got a bee sting while hiking? Crush a plantain leaf and apply—the mucilage soothes while anti-inflammatory compounds reduce swelling and pain. Kids with mosquito bites? Same treatment.
How to Use:
- Fresh poultice for bites/stings: Crush 2-3 fresh leaves (chewing works in an emergency), apply directly to affected area, hold in place 5-10 minutes
- Tea for digestive inflammation: 1-2 teaspoons dried leaves per cup, steep 10 minutes, drink 1-3 cups daily
Evidence Level: Strong traditional use; moderate laboratory evidence for anti-inflammatory effects
Free/Budget Option: 100% foraged—grows everywhere as a “weed”
2. Dandelion (Taraxacum officinale)

Identification:
- Bright yellow flower heads (later become white “puff balls”)
- Deeply toothed leaves (the name means “lion’s tooth” in French) in basal rosette
- Hollow flower stalk that exudes milky white sap when broken (distinctive!)
- Single flower per stalk (no branches)
- Deep taproot
Where to Find: Lawns, meadows, gardens, waste ground
Traditional Use: Used globally as food (greens) and medicine (digestive bitter, liver support) for centuries
Current Research: Studies show dandelion contains inulin (prebiotic fibre), bitter sesquiterpene lactones (stimulate digestion), and significant vitamins/minerals
Why This Matters:
Dandelion greens are nutrient powerhouses—more calcium than spinach, more iron than kale. The bitterness you taste isn’t a flaw—those bitter compounds trigger your body to produce digestive enzymes and bile, improving digestion.
How to Use:
- Young leaves in salad: Harvest in spring before flowers appear (less bitter), add to salads raw or sauté like spinach
- Root “coffee”: Dig roots in autumn (when energy is stored underground), wash, chop, roast at 150°C until dark brown, grind, brew like coffee
- Bitter digestive tonic: Tincture or tea made from roots taken 15 minutes before meals
Evidence Level: Strong traditional use; moderate research evidence for digestive and liver support
Free/Budget Option: 100% foraged, with seasonal timing improving quality
3. Kawakawa (Piper excelsum)

Identification:
- Heart-shaped leaves (very distinctive)
- Dark green, glossy leaves
- Often has holes from kawakawa looper moth (this is normal and actually indicates medicinal potency)
- Aromatic when crushed—peppery, spicy scent
- Small tree/shrub, 1-6 metres tall
- Orange finger-like fruits on female plants (summer)
Where to Find: Throughout North Island and northern South Island; coastal areas, lowland forests, forest edges; prefers partial shade
Traditional Use: Central to rongoā Māori—used for stomach complaints, skin conditions, general wellness, wounds, toothache
Current Research: Studies confirm anti-inflammatory activity from unique compounds (myristicin, yangambun). Antimicrobial properties demonstrated.
Why This Matters—Cultural Respect:
Kawakawa is a taonga (treasure) to Māori. When using kawakawa, you’re engaging with a plant that has profound cultural and spiritual significance. Harvest with respect—take only what you need, thank the plant, and never damage it.
About the Holes:
The holey leaves aren’t damaged—they’re actually considered more potent. The kawakawa looper moth (Cleora scriptaria) co-evolved with this plant. The moth eats certain leaves, and the plant responds by concentrating its medicinal compounds in those leaves. Traditional knowledge says the holey leaves are best.
How to Use:
- Tea for digestion: Simmer 3-5 fresh leaves (preferably holey ones) in 2 cups water for 10 minutes, drink warm
- Skin wash: Strong tea (6-8 leaves per cup) cooled and applied to irritated skin, eczema, minor wounds
Sustainable Harvesting:
- Take only leaves with “spoon-shaped” attachment at the base (these don’t harm plant growth as much)
- Take from multiple plants—2-3 leaves per plant maximum
- Never strip a plant bare
- Avoid harvesting during flowering (spring) when plant is investing energy in reproduction
Evidence Level: Strong traditional use (centuries of rongoā practice); emerging research evidence
Free/Budget Option: Foraged (northern regions) or purchased from Māori-owned businesses ($12-20/50g dried)
4. Cleavers (Galium aparine)

Identification:
- Sticky, Velcro-like feel (the most distinctive feature!)
- Small narrow leaves in whorls of 6-8 around square stem
- Scrambling, clinging growth habit
- Small white flowers
- Tiny round fruits with hooked bristles (stick to clothing)
Where to Find: Damp, shaded areas; hedgerows, forest edges, waste ground
Traditional Use: European and North American folk medicine for lymphatic support, spring cleansing
Current Research: Limited formal studies, but traditional use is well-established. Contains flavonoids and iridoid glycosides.
Why This Matters:
Cleavers is a classic “spring tonic”—harvested when young and tender in spring to support the lymphatic system (your body’s waste-removal network). Think of it as a gentle internal cleanser after winter.
How to Use:
- Fresh juice: Juice fresh herb, take 1-2 tablespoons diluted in water, 1-3 times daily
- Tea: Use fresh herb (dried loses potency quickly)—large handful per cup, steep 10-15 minutes, drink 2-3 cups daily
Timing: Harvest young growing tips in spring when most tender
Evidence Level: Strong traditional use; limited research
Free/Budget Option: 100% foraged in spring
5. Nasturtium (Tropaeolum majus)

Identification:
- Circular “lily pad” leaves with radiating veins
- Petiole (stem) attaches to centre of leaf underside (called “peltate”—very distinctive)
- Bright orange, yellow, or red flowers with distinctive spur at back
- Climbing or trailing growth
- Garden escapee—found on roadsides, waste ground
Where to Find: Grows vigorously throughout NZ as garden escapee
Traditional Use: Used in Andean regions and Europe as food and medicine; recognised for antimicrobial properties
Current Research: Studies show nasturtium contains glucosinolates (same compounds in mustards and broccoli) that convert to antimicrobial isothiocyanates. High in vitamin C.
Why This Matters:
Nasturtium is both food and medicine. The peppery flavour you taste is from glucosinolates—the same compounds that give it antimicrobial properties. Eating nasturtium provides immune support while adding flavour.
How to Use:
- Salad: Add fresh leaves and flowers to salads (peppery kick)
- Pesto: Substitute for basil in pesto recipes
- Seeds: Pickled seeds (green, before mature) are traditional “poor man’s capers”
Evidence Level: Strong traditional use; moderate research on antimicrobial compounds
Free/Budget Option: 100% foraged; also easy to grow from seed ($3-5/packet)
6. Purslane (Portulaca oleracea)

Identification:
- Small, thick, succulent leaves (spatula-shaped)
- Smooth, often reddish stems
- Prostrate growth (lies flat, forms mats)
- Small yellow flowers (5 petals)
- Thrives in hot, dry conditions
Where to Find: Gardens, cultivated fields, cracks in pavement, waste areas
Traditional Use: Used as food globally for millennia; Mediterranean, Middle Eastern, Mexican cuisines
Current Research: Purslane is exceptionally nutritious—one of the richest plant sources of omega-3 fatty acids (alpha-linolenic acid), plus vitamins A, C, E, and antioxidants.
Why This Matters:
Most plant omega-3 sources require processing (flax seeds, chia). Purslane provides them fresh and ready-to-eat. The crisp, slightly tangy flavour is refreshing in salads, and you’re getting anti-inflammatory fats alongside vitamins.
How to Use:
- Raw in salads: Crisp texture, slightly tangy/lemony flavour
- Cooked: Sauté like spinach, add to stir-fries
- Pickled: Traditional in some cuisines
Timing: Harvest in summer when growing vigorously
Evidence Level: Strong nutritional analysis; excellent food source
Free/Budget Option: 100% foraged from gardens (many gardeners consider it a pest!)
7. Yarrow (Achillea millefolium)

Identification:
- Feathery, fern-like leaves finely divided into many tiny leaflets (the species name means “thousand-leaved”)
- Flat-topped clusters of small white (sometimes pink) flowers
- Aromatic when crushed (strong, herbal, slightly spicy)
- Grooved, slightly hairy stem
Where to Find: Meadows, roadsides, dry fields, waste ground
Traditional Use: Used for centuries as wound herb (stops bleeding), fever reducer, digestive aid
Current Research: Contains compounds including achilleine (reduces clotting time), flavonoids (anti-inflammatory), and volatile oils (antimicrobial)
Why This Matters:
Yarrow is traditional battlefield medicine—the genus name Achillea references Achilles, who supposedly used it to treat soldiers’ wounds. Modern research confirms it does speed clotting.
How to Use:
- First aid for cuts: Crush fresh leaves, apply to minor cuts to help stop bleeding
- Tea for fevers/colds: 1-2 teaspoons dried herb per cup, steep 10 minutes, drink hot to promote sweating
IMPORTANT SAFETY WARNING:
Yarrow can look similar to poison hemlock (Conium maculatum), which is deadly. Key differences:
- Yarrow: Hairy, grooved stem; pleasant aromatic scent; flat-topped flower cluster
- Poison hemlock: Smooth, hairless stem with purple blotches; musty, mousy smell; compound umbel flowers
If you see purple blotches on the stem or smell a musty odor, DO NOT use—it may be poison hemlock.
Evidence Level: Strong traditional use; moderate research evidence
Free/Budget Option: 100% foraged
8. Pūhā (Sonchus species – often S. oleraceus)

Identification:
- Shiny, dark green leaves (spear-shaped with slightly prickly/toothed edges)
- Milky white sap when stem or leaf broken
- Yellow dandelion-like flowers
- Rosette growth (though can grow taller)
Where to Find: Disturbed ground, coastal areas, grasslands—common native throughout NZ
Traditional Use: Traditional Māori vegetable (called rauriki or raupeti historically); often served with pork and potatoes
Current Research: Rich in vitamins (A, C, K), minerals, and contains bitter sesquiterpene lactones
Why This Matters:
Pūhā is both free food and traditional Māori kai (food). The bitterness is from the same compound family as dandelion—it supports digestion while providing excellent nutrition.
How to Use:
- Boiled greens: Harvest young leaves, boil to reduce bitterness (vigorously rub together under running water first), serve like spinach
- Traditionally: Cooked with pork (fat balances bitterness)
Timing: Best in spring through midsummer; becomes more bitter in autumn
Cultural Note: This is part of traditional Māori cuisine. While it’s fine to forage and eat, approach it with awareness of its cultural significance.
Evidence Level: Strong traditional use as food; good nutritional profile
Free/Budget Option: 100% foraged
Your First Foraging Trip: A Checklist
Before You Go:
- [ ] You’ve positively identified target plant using multiple sources
- [ ] You know the area is unsprayed (verified with council/landowner)
- [ ] You have permission if on private land
- [ ] You’ve checked it’s not DOC protected area (or have appropriate permission)
- [ ] Weather is suitable (dry conditions for harvesting)
Bring:
- [ ] Field guide(s) or plant ID app
- [ ] Scissors or sharp knife (clean cuts)
- [ ] Basket or paper bag (not plastic—plants “sweat” and degrade in plastic)
- [ ] Gloves (for nettles or prickly plants)
- [ ] Notebook to record locations and observations
While Foraging:
- [ ] Confirm 100% identification before harvesting
- [ ] Take maximum 5-10% of population
- [ ] Harvest from multiple plants, not one
- [ ] Use clean cuts with sharp tools
- [ ] Leave area looking largely undisturbed
- [ ] Note location, date, and conditions in notebook
After Foraging:
- [ ] Process herbs promptly (clean, use, or dry)
- [ ] Store properly (dry location, airtight containers)
- [ ] Update your foraging notes
- [ ] Try small amount first if new to this plant
Seasonal Foraging in New Zealand
Spring (September-November):
Best for: Young greens, spring tonics
- Cleavers (young growing tips)
- Young dandelion leaves (less bitter)
- Young pūhā leaves
- Nettles (top 10-15cm of young plants—wear gloves!)
Summer (December-February):
Best for: Flowers, abundant leafy growth
- Plantain (abundant for bee stings)
- Purslane (thrives in heat)
- Kawakawa (full leaf growth)
- Nasturtium (flowers and leaves)
Autumn (March-May):
Best for: Roots, seeds
- Dandelion roots (energy stored underground)
- Seeds from various plants
Winter (June-August):
Best for: Evergreen plants, identification practice
- Kawakawa (leaves year-round in warmer areas)
- Time to study and identify dormant plants for next spring
Processing and Storage Basics
Drying Herbs:
- Rinse briefly if needed (don’t soak—leaches compounds)
- Pat dry with clean towel
- Spread in single layer on screen or clean cloth
- Place in warm, dark, airy spot (not direct sun—degrades compounds)
- Turn daily
- Ready when leaves crumble easily (3-7 days depending on humidity)
- Store immediately in airtight jars away from light
Signs of Failed Drying:
- Mold (white fuzzy growth)—discard entire batch
- Damp smell—not dried enough
- Leaves bend instead of crumble—not dried enough
Common Beginner Mistakes
Mistake 1: Over-confidence “I think that’s plantain” = Don’t use it yet “I know with 100% certainty that’s plantain based on parallel veins, growth habit, and flowering spike” = Use it
Mistake 2: Harvesting too much Taking half the dandelions in a patch feels like “only half,” but it’s way too much for sustainable practice.
Mistake 3: Assuming clean Even organic gardens can have contaminated soil from historical use. Know the land’s history.
Mistake 4: Learning too many plants at once Learn 3-5 plants thoroughly before adding more. Depth beats breadth.
Mistake 5: Ignoring cultural context Plants like kawakawa and pūhā have deep cultural significance. Harvest and use them with respect for that history.
When NOT to Forage
Don’t forage if:
- You’re not 100% certain of identification
- Population is small or struggling
- Area has been or might be sprayed
- It’s in protected area without permission
- You’re rushed or distracted
- Weather conditions stress plants (severe drought)
Alternative: Many foraged plants grow easily in gardens. Kawakawa, nasturtium, purslane, and herbs all thrive in NZ gardens, giving you clean, accessible sources.
Building Your Practice
Week 1-2: Learn plantain thoroughly
- Find it in 5 different locations
- Photograph it at different growth stages
- Use it for a bite or sting
- Just observe and build confidence
Month 1: Add dandelion and one other plant
- Same deep observation process
- Begin small harvests
- Try in food or as tea
Month 2-3: Expand slowly
- Add 1-2 plants per month
- Join local foraging groups (check Facebook, Meetup)
- Go on guided foraging walks when available
Long-term: Develop relationship with place
- Return to same sites seasonally
- Observe changes through year
- Build knowledge of what grows where

Final Thoughts
Foraging connects you to the living world in immediate, practical ways. That plantain in the crack of the pavement becomes your first-aid kit. The dandelion in your lawn becomes your dinner salad. The kawakawa in the bush becomes your digestive tonic.
Start slowly. Learn deeply. Harvest respectfully.
The land is generous when approached with knowledge and respect.
