NZ Biosecurity: What You Have to Declare
A practical guide to New Zealand's biosecurity rules: what always needs declaring, the risk gear to clean, what happens at the border, and why when in doubt you declare.
Few countries guard their borders against plants, food and animal products the way New Zealand does. Its biosecurity rules are among the strictest on earth, and the checks are real: detector dogs, X-ray machines and inspectors greet you the moment you land. The good news is that the whole thing is straightforward once you understand one fact: biosecurity is part of the NZTD, the digital declaration you complete before you arrive. Get the declaration right and the border is quick.
In brief: New Zealand's biosecurity questions sit inside the NZTD. You must declare all food, plants, seeds, wood and animal products, plus outdoor and sports gear that has touched soil or water. Clean your boots before you fly. Not declaring risky items can bring an instant fine. The golden rule never changes: when in doubt, declare.
Why New Zealand is so strict
New Zealand is a group of islands that spent millions of years cut off from the rest of the world. Its plants, birds and insects evolved in isolation, with no natural defence against the pests and diseases that are common elsewhere. A single foreign fruit fly, seed or soil-borne fungus can devastate an ecosystem that has no way to fight back.
There is a hard economic edge to it too. New Zealand's economy leans heavily on agriculture and horticulture, from dairy and meat to kiwifruit and wine. A biosecurity breach that introduced foot-and-mouth disease or a vineyard pest could cost the country billions and shut export markets overnight. Protecting the border is protecting livelihoods.
That is why the rules can feel severe compared with home. They are not bureaucracy for its own sake. They are a national defence system, and every arriving traveller is part of it.
In short: an isolated ecosystem and an export economy make biosecurity a genuine priority, not a formality.
Biosecurity lives inside the NZTD
Here is the point travellers most often miss: there is no separate biosecurity form. The questions about food, plants and gear are a section of the NZTD itself. When you complete your declaration in the 24 hours before you travel, you answer them there, alongside your customs and immigration details.
That means you cannot skip biosecurity by staying quiet at the airport. Your answers are already recorded and tied to your passport before you land. If you tick "no" to carrying food and an inspector finds a sandwich, the mismatch is on record. Honest answers in the app or on the official site are your protection, not a risk.
Good to know: Because the questions come before you land, take a minute to check your bags as you pack, not at the airport. It is far easier to remember the fruit in a side pocket at home than to explain it to a detector dog on arrival.
If you have not filled in your declaration yet, read how to complete the NZTD and make sure you answer the biosecurity questions carefully rather than rushing them.
In short: biosecurity is a built-in part of the NZTD, answered before arrival and linked to your passport.
What you must always declare
Some categories always need declaring, every time, no exceptions. Reach for the "yes" button whenever you are carrying any of the following:
- Food of any kind — cooked, raw, packaged, fresh, dried or snacks, including airline food you kept.
- Fruit and vegetables, including a single apple left in your bag by accident.
- Honey and other bee products.
- Meat, dairy and other animal products, whether fresh, dried, canned or vacuum-packed.
- Plants, parts of plants, cut flowers and seeds of any type.
- Wood and wooden items, bark, and things made from untreated timber.
Declaring an item does not mean losing it. Many packaged, low-risk foods are cleared and handed straight back. Declaring simply lets an officer decide, instead of you gambling on a rule you may not know.
A few everyday items trip people up more than any others, because they feel too ordinary to count:
- The apple, banana or sandwich picked up at your departure airport or handed out on the plane.
- Dried fruit, nuts and trail mix bought for the flight and half-finished.
- Spices, herbal teas and stock cubes tucked into a bag as a gift.
- Fresh flowers or a plant cutting carried as a present.
- A wooden carving or instrument bought as a holiday souvenir.
None of these are automatically banned, but every one of them must be declared so an officer can look. Waving them through on your own judgement is exactly what the fines are designed to punish.
Good to know: "Food" is broader than people expect. Herbal teas, spices, dried mushrooms, homemade snacks and traditional medicines all count. If it grew, was an animal, or came from a hive, declare it.
In short: food, fruit, honey, animal and plant products, seeds and wood always get declared, no matter how small.
Risk gear: the outdoor and sports trap
The category that catches experienced travellers is used outdoor and sports equipment. New Zealand is a hiking, camping and adventure destination, and gear that touched soil or water abroad can carry seeds, spores or organisms in the mud.
Declare anything in this list if it has been used outdoors:
- Hiking boots and camping equipment — tents, pegs, poles, mats.
- Golf clubs and golf shoes that have crossed a fairway.
- Bicycles and bike tyres caked with trail dirt.
- Fishing and diving gear — waders, nets, wetsuits, fins that have touched fresh or salt water.
- Used gardening tools and anything with soil on it.
The common thread is contact with soil or water. Clean equipment is usually fine; dirty equipment is a risk. That is why cleaning before you pack matters so much.
Good to know: If you have been on a farm, in a forest or near a river in the days before you fly, mention it. Officers pay particular attention to gear and footwear that has been in rural or wilderness areas, where seeds and organisms are most likely to hitch a ride.
In short: used boots, camping, golf, cycling, fishing and diving gear that met soil or water must be declared.
Clean your footwear before you travel
The simplest way to avoid trouble is to clean your gear at home, before it ever reaches your suitcase. Give hiking boots, trainers and any outdoor footwear a proper scrub, paying attention to the tread where soil hides. Do the same for tent pegs, bike tyres and fishing gear.
A quick pre-pack routine covers almost everything:
- Brush out the tread of every pair of shoes until no soil remains.
- Shake out tents and bags and wipe down pegs and poles.
- Hose down bike tyres and dry them before packing.
- Rinse and dry fishing and diving kit, checking seams and straps for grit.
Arriving with visibly clean equipment speeds you through inspection. Arriving with mud in your boot tread invites a closer look, a possible clean-down at the airport, and sometimes treatment or a delay. A ten-minute scrub at home saves you all of it.
Good to know: Even clean gear should still be declared if asked about it. Declaring plus a clean item is the fastest path through; hiding a dirty one is the slowest.
In short: scrub boots and outdoor gear before you pack, then declare them anyway.
Medication and personal items
Prescription and personal medicines deserve their own mention, because they sit across biosecurity and customs. Carry them in their original packaging, bring enough only for your personal use, and keep a copy of the prescription or a doctor's letter for anything unusual. Some medicines that are routine at home are controlled in New Zealand.
Herbal and traditional remedies can also fall under biosecurity if they contain plant or animal material. Watch out in particular for:
- Traditional medicines containing dried herbs, roots or bark.
- Supplements made from plant extracts or animal by-products.
- Teas and tonics with whole botanical ingredients.
If your remedy includes seeds, dried plants, or animal parts, treat it like food and declare it. For the customs side of medicines and other goods, see the guide to New Zealand customs allowances.
In short: carry medicines in their original packaging with documentation, and declare herbal remedies that contain plant or animal material.
Instant fines and why "no" is expensive
New Zealand backs its rules with instant fines. Fail to declare a risky item and an officer can issue an on-the-spot infringement fee, with far larger penalties and even prosecution for serious cases. Treat any specific figure you read as a guide that can change, and confirm current amounts on the official channels; the principle, though, is fixed: not declaring costs money, declaring does not.
The maths is simple. Declare an apple and, at worst, you hand it over and walk on. Hide it and you risk a fine many times the price of your whole trip's snacks. There is no penalty for declaring something that turns out to be allowed, so there is never a reason to stay quiet.
Penalties climb with intent. In rough order of seriousness:
- An honest declaration of a risk item: no penalty, the item is assessed and often returned.
- A forgotten item you own up to at inspection: usually just disposal, sometimes a warning.
- An undeclared item found by a dog or X-ray: an on-the-spot infringement fee.
- Deliberate concealment or commercial smuggling: far larger fines and possible prosecution.
The line between the free outcome and the expensive one is simply whether you declared. That single choice, made in the app before you fly, is what protects you.
In short: undeclared risk items bring instant fines; declaring is always free of penalty.
Item-by-item: declare, clean or likely removed
The table turns the rules into quick decisions. It is a guide, not the final word: an officer always makes the call on the day.
| Item | Declare? | Clean first? | Likely outcome |
|---|---|---|---|
| Fresh fruit or vegetables | Yes | No | Usually removed |
| Packaged snacks, biscuits | Yes | No | Often allowed after check |
| Honey and bee products | Yes | No | Often removed |
| Meat, dairy, dried animal products | Yes | No | Usually removed |
| Seeds, bulbs, cut flowers | Yes | No | Often removed or treated |
| Wooden carvings, untreated wood | Yes | No | Inspected, sometimes treated |
| Used hiking boots | Yes | Yes | Allowed if clean |
| Camping and fishing gear | Yes | Yes | Allowed if clean |
| Golf clubs, bicycles | Yes | Yes | Allowed if clean |
| Prescription medicine | Yes | No | Allowed with documentation |
In short: food is usually taken, gear is usually kept if clean, and everything on this list gets declared.
The golden rule: when in doubt, declare
If you remember nothing else, remember this: when in doubt, declare. There is no downside. Declaring an allowed item costs you a few seconds and an honest "yes". Failing to declare a banned one costs you a fine and a bad start to the trip.
Travellers get into trouble by trying to judge the rules themselves, deciding a sealed packet or a clean-looking boot "surely counts as fine". Do not judge; declare, and let the officer judge. That is exactly what the biosecurity section of the NZTD is for.
Good to know: If you find a forgotten apple or muesli bar after you have submitted your declaration, you can still use the amnesty bins at the airport before inspection. Binning it is free; carrying it through is not.
In short: declaring is always safe and free; guessing is where the fines come from.
What happens at the biosecurity check
After you collect your bags, you pass through the biosecurity control before leaving the airport. Three things may happen, often at once:
- Detector dogs work the baggage hall, trained to sniff out food, plants and animal products, even sealed ones deep in a bag.
- X-ray machines scan luggage for organic material and undeclared items.
- Inspectors may ask about your declaration, open bags, and check the tread of your boots or the state of your gear.
If everything matches your NZTD, you are through in moments. If you declared a risk item, an officer decides whether to return it, treat it or dispose of it. If you failed to declare something the dogs or X-ray find, that is when fines apply. The system rewards honesty and speed, and it is fast for the vast majority of travellers.
Good to know: Being directed to an inspection lane is not a sign you have done something wrong. Officers pull travellers aside routinely, and a clean, honestly declared bag clears quickly. The check exists to protect the country, not to catch out careful travellers.
For the wider picture of landing, read the eGate and arrival process, and to avoid slip-ups, the common NZTD mistakes.
In short: dogs, X-ray and inspectors verify your declaration; matching answers mean a fast, painless clearance.

FAQ: New Zealand biosecurity and the NZTD
Is biosecurity a separate form from the NZTD?
No. The biosecurity questions are a section within the NZTD itself. You answer them when you complete your declaration before travelling, alongside customs and immigration details.
Do I really have to declare a single apple?
Yes. Any fresh fruit counts, even one apple left in your bag by mistake. Declaring it costs nothing; carrying it undeclared can trigger an instant fine, so always declare or bin it first.
Will declaring food mean I lose it?
Not always. Many packaged, low-risk foods are checked and handed straight back. Fresh fruit, meat, honey and plant material are more likely to be removed, but declaring is still the safe choice.
What outdoor gear needs declaring?
Any used equipment that touched soil or water: hiking boots, tents, golf clubs, bicycles, and fishing or diving gear. Clean it before you travel and declare it anyway to clear inspection quickly.
How much is the fine for not declaring?
New Zealand issues instant infringement fees, with much larger penalties for serious cases. Treat any specific amount as a guide that can change and confirm current figures on the official channels.
Can I bring my prescription medicine?
Generally yes, in its original packaging and in quantities for personal use, with a copy of the prescription or a doctor's letter for anything unusual. Some medicines routine elsewhere are controlled in New Zealand.
Are herbal or traditional remedies allowed?
It depends on their contents. Remedies containing seeds, dried plants or animal parts fall under biosecurity and must be declared. Declare them like food and let an officer assess them.
What are the detector dogs looking for?
They are trained to detect food, plants and animal products, including sealed items deep inside luggage. If a dog signals your bag, an inspector will check it against your declaration.
What if I forget to declare something and only remember at the airport?
Use the amnesty bins before the inspection point to dispose of forgotten food for free. Binning a risk item is always cheaper than being caught with it undeclared.
Does clean gear still need to be declared?
Yes. Cleaning reduces the risk and speeds you through, but you still declare used outdoor gear. Declaring a clean item is the fastest route; hiding a dirty one is the slowest and riskiest.
