Choosing a cremation urn is one of those decisions that feels bigger than it should be, partly because most people have never done it before, and partly because it matters. The right urn is one you'll feel settled about — not one you rushed into or second-guessed later.

This guide covers everything you need to make a confident choice: size, material, type, purpose, budget, and the questions worth asking before you commit. If you're already clear on one aspect, use the section headings to jump to what you need.

Step One: Decide What the Urn Is For

Before thinking about size or material, the most useful first question is: what will this urn be used for?

The answer shapes almost every other decision.

Keeping at home. The most common choice. The urn will be displayed in a meaningful place — a shelf, a mantelpiece, a bedside table. Size, weight, and appearance all matter. The urn needs to suit the space and feel right to the people who will see it every day.

Burial. Some families choose to inter the urn in a cemetery plot, a mausoleum, or a columbarium niche. If this is the plan, the urn needs to fit within the niche dimensions — check with the cemetery before purchasing. Not all materials are suitable for burial; biodegradable urns are designed specifically for this purpose.

Scattering. If the intention is to scatter the ashes, a scattering tube is often more practical than a traditional urn. Some families keep the urn at home for a period before scattering — in which case a standard urn still makes sense.

Sharing among family. If more than one family member wants to keep a portion close, an adult urn for the main set of remains combined with keepsake urns for individual family members is the most common approach. More on this in the keepsakes section below.

A combination. Many families scatter some ashes, keep some at home, and give keepsakes to family members. There's no rule that says you must choose one option.

Step Two: Get the Size Right

Once you know the purpose, size is the most practical decision to get right before anything else. An urn that's too small is the one problem that can't be solved after the fact.

The sizing rule

For every kilogram of body weight, cremated remains take up roughly 2.2 cubic inches of space. Someone who weighed 70kg produces around 154 cubic inches of remains — approximately 2.5 litres.

One thing most guides don't mention: the remains are returned in a sealed bag inside a temporary container. That bag takes up additional space — typically 10 to 15 percent more than the weight formula suggests. This is why going slightly larger than the calculation indicates is always the sensible call.

Our full urn sizing guide includes a complete weight reference table and covers the 92kg threshold where extra large urns become necessary.

Urn types by size

If you're choosing for a pet, the same sizing rule applies — roughly 2.2 cubic inches per kilogram of body weight.

Step Three: Choose the Right Material

Material affects how the urn looks, how it feels to hold, how long it lasts, and in some cases whether it's suitable for burial. This is where personal preference plays the biggest role.

Brass. A traditional choice with warm tones and a solid, weighty feel. Brass urns are durable and well-suited to long-term display. Many families choose brass for its combination of craftsmanship and longevity.

Aluminium. Lightweight, versatile, and available in the widest range of colours and finishes. Aluminium urns are the most popular choice across our range because they combine durability with a broad variety of styles.

Cloisonné. A hand-crafted enamel finish applied over a metal base, producing intricate patterns and rich colours. Cloisonné urns are often chosen as heirloom pieces — decorative as well as meaningful.

Biodegradable. Designed to break down naturally over time, biodegradable urns are the appropriate choice for burial in the ground or water interment. If burial or scattering at sea is the plan, check whether a biodegradable urn is required or preferred.

For a detailed comparison of the two most popular materials, our brass vs aluminium urns guide covers the differences in weight, finish longevity, and which suits different purposes.

Step Four: Choose the Type of Urn

Adult Urns

Adult urns hold a complete set of cremated remains. They're the primary urn for most families — the one that stays in the home or is interred. Standard capacity is 200 cubic inches (approximately 3.3 to 3.4 litres). We carry traditional, contemporary and decorative styles across a wide range of colours and finishes.

Keepsake Urns

Keepsake urns hold a small portion of remains — typically a few tablespoons — so that multiple family members can each keep a piece of their loved one close. They sit alongside a primary adult urn rather than replacing it.

Keepsakes are one of those options many families don't know about until they're already managing arrangements. If more than one person wants to keep a personal memorial, keepsake urns are the most practical and meaningful way to make that possible.

Companion Urns

Companion urns hold the remains of two people — typically a couple — in a single urn. They may have two separate compartments or a shared interior, depending on the design. Capacity is generally 400 cubic inches or more. If the wish is for two people to remain together, a companion urn is worth considering at the time of the first arrangement, as it avoids having to transfer remains later.

Child, Baby and Infant Urns

Child urns are sized for older children, with capacity typically between 50 and 120 cubic inches. We also carry baby and infant urns for younger children. The same sizing rule applies — approximately 2.2 cubic inches per kilogram of body weight.

Large and Extra Large Urns

For adults who weighed over 92kg, a standard adult urn may not be sufficient once the sealed bag from the crematorium is accounted for. We have a small selection of extra large urns for this purpose — contact us directly and we'll help you find the right fit.

Cremation Jewellery

Cremation jewellery holds a small portion of ashes in a pendant, ring, bracelet or charm. It's not a replacement for an urn — it's an addition, for someone who wants to carry their loved one with them every day.

Step Five: Consider Where the Urn Will Live

If the urn is staying in the home, think briefly about where it will be placed before finalising your choice.

A large, ornate urn on a small shelf can feel overwhelming. A modest keepsake-sized urn in a large room can feel lost. Neither is wrong — but matching the urn to the space it will occupy means you're less likely to feel unsettled about it later.

Consider the light in the space. Cloisonné and metallic finishes catch light differently to matte finishes. A finish that looks one way in a product photo may look different in a particular room.

If the urn is for a columbarium niche, measure the niche interior before purchasing — there is no industry standard niche size. Niche dimensions vary significantly between cemeteries.

Step Six: Set a Realistic Budget

Cremation urn prices in NZ vary significantly by material, craftsmanship, and whether personalisation is included. Our guide to how much urns cost in NZ covers what to expect across different categories.

As a general orientation: keepsake urns sit at the lower end of the price range. Adult urns in aluminium are mid-range and offer the widest choice. Brass and cloisonné urns tend to be priced higher because of the materials and craftsmanship involved. Companion urns are priced higher again given their size.

A more expensive urn is not necessarily a better tribute. The right urn is the one that feels appropriate for the person and the family — regardless of where it sits in the price range.

Frequently Asked Questions

What size cremation urn do I need in NZ? Multiply the person's weight in kilograms by 2.2 to get the approximate cubic inches of remains needed. A 70kg person produces around 154 cubic inches. Most standard adult urns hold 200 cubic inches, which comfortably fits the remains plus the sealed bag returned by the crematorium. For anyone who weighed over 92kg, a larger urn is recommended. See our full urn sizing guide.

What is the best material for a cremation urn in NZ? There is no single best material — it depends on purpose and preference. Aluminium offers the widest range of styles and is the most popular choice. Brass is traditional and durable. Cloisonné is decorative and suited to display as an heirloom. Biodegradable materials are appropriate for burial or water interment.

What is the difference between an adult urn and a keepsake urn? An adult urn holds a complete set of cremated remains — typically 200 cubic inches or approximately 3.4 litres. A keepsake urn holds a small portion of remains, usually a few tablespoons, and is designed for individual family members to keep a personal memorial alongside a primary urn.

Can more than one family member have an urn? Yes. The most common approach is one adult urn to hold the full remains, with as many keepsake urns as there are family members who want one. Cremation jewellery serves a similar purpose for those who prefer something wearable.

What is a companion urn? A companion urn holds the remains of two people, typically a couple. Capacity is usually 400 cubic inches or more. Some designs have two separate compartments; others share a single interior.

Do I need a special urn for burial in NZ? If the urn is being interred in a cemetery or columbarium niche, check the niche dimensions before purchasing — there is no standard size. For ground burial, some cemeteries require a biodegradable urn or an urn vault. Confirm requirements with the cemetery directly before ordering.

Can I return an urn if it's not right? Yes. We accept returns within 30 days of delivery for unused items in original packaging. Personalised items cannot be returned for change of mind. Full details on our refunds and exchanges page.

How long do cremated ashes last in an urn? Indefinitely, when stored properly in a sealed urn kept indoors away from direct sunlight and moisture.

A Final Note

There is no perfect urn. There is only the one that feels right for the person it represents and the family who will live with it. If you're uncertain, take your time — the ashes are safe while you decide.
