Field guide
Brushtail possum
The most widespread and most recorded pest mammal in New Zealand. Possums browse native forest, prey on eggs and chicks, and carry bovine TB, which is why they are the primary target of most 1080 operations.

Trichosurus vulpecula
- Best season
- Year-round; fur prime in winter
- When they move
- Strictly nocturnal
- Country
- Everywhere with trees - forest, farm shelterbelts, suburban margins
- How hard
- Easy, and the species most landowners will thank you for.
How they behave, and what that means
Hunted at night by lamp or by trapping rather than stalked. They freeze in a light rather than fleeing, and they follow the same runs between trees night after night, which is what makes trapping effective.
Sign to look for
Scratch marks on trunks, browsed new growth, droppings under favoured trees and loud rasping calls at night
Tips
- Shelterbelts and bush edges hold more than the middle of a block.
- Eyes reflect bright in a lamp - the giveaway is the height off the ground.
- Fur has a market; ask the landowner whether they want the carcasses left.
- Possums are the main 1080 target, so dogs and treated blocks do not mix.
Where you’ll find them
Nocturnal and near-ubiquitous. Usually controlled by trapping or poison rather than hunted, though shooting is common on farmland at night.
Dogs and 1080
Possums are the main target of 1080, so possum country and 1080 country are effectively the same country. This is the species whose control most affects dog safety.
Check 1080 operationsWhy people shoot them
Fur, and control. The carcass is usually left.
Possum fur has real value and is the reason many people do it at scale. Otherwise it is straight control — possums are the main driver of bovine TB spread and do serious damage to native forest.
Any farmer will take help with possums. If you are plucking fur, say so — it changes how long you will be there and where.
What to shoot a brushtail possum with
A .22 rimfire is the standard tool, and for most of this work it is the right one.
These are small, thin-skinned animals usually taken close, often at night with a light. Power is not the problem — accuracy and knowing where the round stops are. A rimfire round carries well over a kilometre.
What people use
Anything marked private land only is below DOC’s minimum and may not be used for hunting on public conservation land — lawful on a farm with the owner’s permission, not lawful on DOC land. If a trip covers both, take the centrefire.
The risk here is the backstop, not the animal. Rimfire rounds ricochet off hard ground and skip off water. Note where you are, too: a .22 is the right tool on a farm and unlawful for hunting on public conservation land, where nothing below .222 Remington is permitted.
On public conservation land, there is a legal minimum
Only centre fire rifles of calibre .222 Remington or larger may be used for hunting, or crossbows and bows that meet the minimum standard specified by DOC.
Hunting with any shotgun, rimfire rifle, .17 or .22 hornet calibre, air rifle or tracer and incendiary type ammunition is forbidden.
That is DOC’s hunting permit condition, and it applies wherever the permit does. On private land the landowner sets the terms — but the reason for the rule does not change with the fence line. Read the permit conditions

- Effective game killing — Terminal Ballistics Research Nathan Foster, in Taranaki, has spent decades documenting what bullets actually do to these animals — red deer, tahr, chamois, sika, pigs, goats. If you read one thing about this, read him rather than an overseas chart built around whitetail and elk. He sells books alongside the free knowledge base, which is worth knowing; the research is still the best there is.
- Cartridge-by-cartridge research Already own a rifle? Start here and read about what you have, rather than about what to buy.
- Matching cartridge to game — Hunter-ed The platform US state agencies use for hunter education. Good on the principle.
These are starting points, not prescriptions. Shot placement and bullet construction beat calibre nearly every time, and a rifle you shoot well beats a more powerful one you flinch with — which is an argument for practising more, not for taking less gun.
After the shot
Nobody is eating this one, so the job is the fur.
- Standing over it
- Skin it while it is warm — the pelt comes away far more easily in the first hour, and that is the only part with any value.
- Eating it
- Legal to eat and almost nobody does. There is no market for the meat and no processor takes it.
Possums are the main wildlife carrier of bovine TB in New Zealand, which is why they are poisoned and trapped at the scale they are. Handle them with gloves, especially skinning, and do not do it with open cuts on your hands.
Getting it out, butchered, and what the law says about selling it
Before you go
Seasons, permits, firearms rules and area closures differ by region and by land status, and they change. We don’t publish those — a stale copy of a rule is worse than none. We do map the land itself: boundaries, public conservation land and unformed legal roads. So find the country here, and check the rules with whoever sets them:
And whatever the rules say
Nobody regulates this part, so nobody else will tell you. It is what experienced hunters do without thinking about it.
- Identify your target beyond all doubtNot the shape, not the colour, not the sound, not the movement — the animal. Most people killed hunting in New Zealand are shot by another hunter who was sure. If you are talking yourself into it, that is the answer.
- Assume you are spending the night outOn every trip, including the two-hour one. Carry a survival bag, a warm layer that works wet, food you do not intend to eat and a head torch with spare batteries. People are late constantly and it only matters when they are not carrying this.
- Assume you are getting wetRain, river, or sweat — one of the three, every time. Wool or synthetic next to the skin and never cotton, which stops insulating the moment it is damp and then takes your heat. Keep one dry layer sealed in a bag and do not touch it until you need it.
- Carry a knife, and a way to make fireThe knife is for the animal, and for cutting yourself free of something, and for making a shelter. Fire is what turns a bad night into an uncomfortable one. Both live on you, not in the pack you might put down.
- Carry a PLBThere is no cell coverage where you are going. A personal locator beacon is the difference between a search and a rescue, they can be hired cheaply, and it is the single most useful thing in the pack. Take it out of the pack lid and put it on you.
- If you are unsure about the river, do not cross itDrowning is the other thing that kills hunters here. A river that is up will still be up in the morning, and it comes down faster than you think. Waiting is almost always available; crossing is not always survivable.
- Tell someone, and be honest about the timeNot the time you hope to be out — the time after which something has gone wrong. Then mark yourself back, because a search that starts for somebody sitting in the pub is a search that will not be taken seriously next time.
The firearms rules themselves are in the Firearms Safety Code , and Mountain Safety Council teach the bush side properly. Both are worth an evening before your first trip somewhere new.
Thermals, on public conservation land
Three separate rules that get argued about as though they were one. These are conditions of a DOC hunting permit, so they apply to public conservation land — every line in quotation marks below is DOC’s wording, not ours.
- Permitted: Hand-held, in daylight, to find animals
Hand-held monocular and binocular thermal imaging equipment is permitted for the use of searching and locating wild animals during daylight hours.
- Prohibited: Anything mounted on the rifle
Hunting or discharging a firearm that has thermal imaging, night vision, or spotlight equipment attached.
- Prohibited: After dark, at all
Having a loaded firearm or discharging a firearm during the hours of darkness (half an hour after sunset to half an hour before sunrise).
- Prohibited: Spotlights and any other artificial light
Hunting using spotlights, torches, night vision equipment, vehicle headlights, or any other artificial light source.
Read the permitted wording again: searching and locating. A thermal tells you something warm is there, not what it is. DOC’s own line when they announced the change was that hunters “will then still need to identify their target beyond all doubt before taking their shot”, and that has not moved.
Check the date on whatever you were told. Hand-held thermal only became permitted on 1 June 2024. A lot of confident advice still in circulation predates that — and a lot of people heard “thermals are legal now” and took it to mean the one on the rifle.
On private land there is no DOC permit, so these conditions are not what governs. The landowner sets the terms and every firearms and target-identification rule applies exactly as it does anywhere else. We are not going to tell you more than that, because it would be us guessing about your block.
