Is there a double glazing grant in New Zealand?

No. There is no government grant for double glazing in New Zealand. EECA's Warmer Kiwi Homes programme co-funds ceiling and underfloor insulation and high-wall heat pumps, but not windows (EECA, checked 9 October 2026). Glazing is usually paid for from savings, a bank's green home top-up loan, or, in a few regions, a council scheme repaid through your rates.

What does Warmer Kiwi Homes actually fund?

Warmer Kiwi Homes is EECA's co-funding programme for older, owner-occupied homes. It covers ceiling and underfloor insulation, high-wall heat pumps, and the small access and repair jobs needed to install them. Wall insulation is not funded, and neither is glazing of any kind, retrofit or replacement.

Who is eligible for Warmer Kiwi Homes?

The home has to be owned and lived in by the person applying, and built before 2008. On top of that you need a Community Services Card or SuperGold Combo card, or to live in an area EECA classes as low or middle income. Rentals, baches, holiday homes and homes owned by a business are excluded.

That matters for glazing even though windows aren't covered. If your ceiling or underfloor isn't insulated and you qualify, that is the cheapest heat you will ever buy back, and it should come before new glass. Windows are a smaller share of the house than the ceiling and floor, and the grant makes the insulation far cheaper per room warmed.

So what does help pay for double glazing?

Three routes come up again and again, none of them a grant in the sense people search for.

• A green or healthy-home loan from your bank. Most of the main banks offer a low- or zero-interest top-up on an existing mortgage for energy upgrades, and double glazing is commonly on the eligible list. Rates, caps and terms change often, so read your own bank's current page rather than a comparison site's summary.
• A council scheme repaid through your rates. Some regional councils have run voluntary targeted rate schemes, where the council pays the installer and you repay it on your rates bill over several years. Hawke's Bay Regional Council's Sustainable Homes programme has included double glazing. Ask your own regional council whether anything is open now; these schemes open and close.
• Doing it in stages. Glazing is one of the few renovation jobs that splits cleanly by room. Retrofitting the bedrooms and living area this winter and the rest next year usually adds little to the total.

Why do some websites say there is a double glazing grant?

Mostly because the search is international. The UK and Ireland both have schemes that touch windows, and their pages rank for the same words. Some New Zealand installer pages also say 'finance available' close to the word 'grant', which reads like funding but is a payment plan. If a page promises a New Zealand government double glazing grant, ask it to name the programme and link to it.

What should I do before spending on windows?

1. Check the ceiling and underfloor. If either is missing or thin, see whether you qualify for Warmer Kiwi Homes and do that first.
2. Stop the draughts. Close-fitting, floor-length lined curtains with pelmets are EECA's own first step for windows, and closing them before dark is free.
3. List the windows in the rooms you use most, and price those with our calculator.
4. Read the cost guide so you know what a fair per-window and per-m² figure looks like before any quote arrives.
5. Book a measure when you are ready to turn the range into one fixed number.
