Fish & Koi Cremation in Wellington: what to know
Prices for fish cremation in Wellington follow the smallest weight band on a provider's list, so even a tiny fish usually costs the provider's minimum for a private cremation. That's why honest providers will tell you what to expect back before you pay. For a small fish, communal cremation or a garden burial is often the more sensible choice.
In Wellington, as elsewhere, the most important rule for fish keepers is about living fish: don't release them, and don't empty a pond or tank into a creek, lake or drain. Non-native fish can spread disease and crowd out wildlife. For fish that have died, burial and cremation are both straightforward; the local rules below cover the details.

Local attitudes to cremation
In Wellington, about 69%[1] of people are cremated. That middle ground means most people are comfortable with cremation without it being automatic. For a fish, that's a helpful place to be: nobody expects a particular choice, and providers are used to hearing different requests. Decide by size. Larger koi and goldfish suit cremation; the smallest fish often suit a burial, a planter or a communal cremation.
That Wellington rate is a human statistic published by The Spinoff, citing FDANZ 2023 Funeral Industry Trends Report (2023); there is no pet equivalent, so we use it as a signal of how families here already think.
Why a small fish still has a minimum price
Listed prices vary widely by Australian state, from AUD 150 at the low end in NSW to well over AUD 1,000 for large-animal packages[2], so a fish-sized quote in Wellington could fall almost anywhere in the small-pet band. New Zealand has fewer providers, so the choice is narrower. Either way, get the lowest-band price in writing, and check whether it includes the container or only the cremation.
In Australia, a survey of listed prices puts individual cremation for pets up to 5 kg at a median of about AUD 412[3], and fish sit well under that weight. Communal cremation starts from AUD 80[4]. With 11%[5] of Australian households keeping fish, providers are used to the question, but always ask what they expect to return for a small fish.
| Service | Price | Notes |
|---|---|---|
| Australia, individual, up to 5 kg | Median about AUD 412 | Range AUD 295 to 612 |
| Australia, communal | from AUD 80[4] | No ashes returned |
| Auckland, 2–7 kg pet | NZD 305 individual / NZD 55 communal | One provider's listed prices |

The legal side of losing a fish in Wellington
You don't need a permit to have a fish cremated, but what you do with the body or the ashes can be governed by local rules. The most important one for fish keepers applies to living fish: never release a fish, or empty a pond or tank, into a creek, lake or drain. Many places restrict releasing non-native fish because they can spread disease and crowd out wildlife.
In New Zealand, koi carp are classed as a noxious fish, so goldfish are the typical pond fish and koi ponds are rare. Never release any aquarium or pond fish into waterways. Councils set the rules on home burial, and a garden or planter burial is common for small fish. Ask any crematorium whether it accepts fish before you book.
Step by step, from tank to goodbye
- If a big koi is going for private cremation, take its length and get a rough weight by standing on bathroom scales holding the bagged fish.
- Photograph its markings before it goes in the freezer. A photo can be checked against the paperwork later, and many families treasure it regardless.
- Wrap it in an old towel inside two strong bags and freeze it lying flat so it fits a cooler later.
- Call a provider that has cremated fish before and ask how much ash it expects and how it tracks each pet.
- Work out the urn size using the urn size calculator first, so you don't buy the wrong one.
- Drive it over in an insulated box with frozen gel packs, and think ahead about a home for the ashes, whether that's indoors on a shelf, out in the garden or beside the pond.
Remembering your fish in Wellington
Many families in Wellington mark a fish's life beside the pond: a flat engraved stone at the edge, a new water lily or a marginal plant bought in its name. If you have ashes from a large koi, you can scatter a little in the garden around the pond, rather than into the water, and keep the rest in a small urn or glass keepsake.

Questions people ask
Where can I find out why my fish died in Wellington?
An aquatic vet is the best first stop, and pond clubs or aquarium shops generally know one. Some university vet schools and fish health labs also examine samples. Keep the body chilled in the fridge rather than frozen and call quickly, since ice crystals ruin the tissue a pathologist needs. Knowing the cause can protect the fish you still have.
Can I keep a koi's ashes outdoors by the pond in Wellington?
Yes, if the container can cope with the weather. Choose a sealed, frost-proof urn in stone, metal or glazed ceramic, or place a small inner urn inside a hollow garden ornament. Ordinary wood and unglazed pottery crack in freezing weather and fade in strong sun. Set it on a firm base away from the splash zone, and consider burying most of the ashes and keeping only a little on display.
Do pet crematories in Wellington accept fish?
Many do, particularly for larger fish such as koi and pond goldfish. Some decline very small fish because there's nothing meaningful to return, or offer communal cremation or a symbolic return instead. Call ahead with your fish's length and weight and ask what they'd expect to give back.
Why do pond fish die in hot weather in Wellington?
Warm water holds less oxygen, and on hot, still nights levels drop lowest around dawn. In hot parts of Wellington, such as Wellington where summer highs average about °F, an air pump or fountain helps, and a dead fish should be removed and frozen promptly.
How many communities do you cover in Wellington?
We currently have local fish aftercare guides for 1 communities in Wellington, including Wellington. Each page covers local weather and timing, prices, rules for burial and scattering, and how to find a provider that accepts fish.
Can I scatter my koi's ashes in a lake or river in Wellington?
It depends on who manages the water, and some public waters require permission. Scattering around your own pond, in the garden rather than into the water, avoids the question and keeps the memorial close. If you use a public place, choose a quiet spot and check the rules first.
