Green loan interest rate

New Zealand’s government supports warm, energy-efficient homes through a mix of direct grants, weekly payments, low-interest green loans and consumer-protection rules. Together they cut up-front costs, lift the standard of rentals and shield households from runaway power bills.

The four flagship programmes are Warmer Kiwi Homes, the Winter Energy Payment, the Healthy Homes Initiative and the Community Renewable Energy Fund. Around them sit major-bank green loans at 1% interest, regional council top-ups, and a growing set of regulatory protections under the Electricity Authority.

6 things to check

How to qualify for NZ energy support

Each scheme has its own eligibility rules — but most flagship programmes share the same handful of criteria.

Income or Community Services Card

Warmer Kiwi Homes targets homeowners with a Community Services Card, SuperGold combo card or who live in a low-income area.

You own the home

Most grants require you to own and live in the property. Rentals are covered separately through the Healthy Homes Standards on the landlord.

Age of the home

Warmer Kiwi Homes is for houses built before 2008. Older homes lose the most heat and benefit the most from insulation and heat pumps.

You receive a qualifying benefit

The Winter Energy Payment is paid automatically to NZ Super, Veteran’s Pension, Jobseeker, Sole Parent and Supported Living recipients.

You bank with the right lender

Green home loans are only available to existing customers of Kiwibank, ANZ, BNZ or Westpac. The 1% rate is conditional on approved upgrades.

Your project is on the list

Approved upgrades typically include insulation, heat pumps, double glazing, solar PV, batteries, EVs and water heating. Cosmetic work does not qualify.

How much you get

How much is the Winter Energy Payment in 2026?

The Winter Energy Payment is paid automatically from 1 May to 1 October to eligible NZ Super, Veteran’s Pension and main benefit recipients. It is not means-tested, not taxable, and does not affect other entitlements.

$20.46

Single, no dependants / week

$31.82

Couple or dependants / week

$700

Max season total / couple

Payments stop automatically on 1 October. If you do not want the payment, you can opt out through MyMSD.

Why these schemes exist

Why government energy support matters in Aotearoa

Three structural problems explain why New Zealand commits hundreds of millions every year to household energy support.

1

Cold, leaky housing stock

Around half of New Zealand’s homes were built before insulation was compulsory in 1978. Many remain hard to heat, damp and expensive to run year-round.

2

High power bills

The average Kiwi household spends roughly $2,400 a year on electricity. Wholesale prices are set by the highest-cost thermal plant, keeping retail rates elevated.

3

Climate commitments

Aotearoa has a 2050 net-zero target. Insulating homes, electrifying heat and adding rooftop solar are the cheapest ways to cut emissions and save households money.

Energy schemes FAQ

The Selectra expert answers your questions

Apply directly through EECA’s Warmer Kiwi Homes service or by calling 0800 358 676. You will need to confirm you own the home, that it was built before 2008, and that you hold a Community Services Card, SuperGold combo card, or live in an area targeted by the programme. Once approved, an EECA-accredited installer comes out, surveys the home and books the work.

No, it is paid automatically. If you receive NZ Super, Veteran’s Pension, Jobseeker, Sole Parent or Supported Living Payment, Work and Income tops up your usual payment from 1 May to 1 October each year. You can opt out at any time through MyMSD if you would rather not receive it.

Some, yes. Renters benefit from the Healthy Homes Standards, which force the landlord to install insulation and an approved heat source. Renters with children may also qualify for the Healthy Homes Initiative through a GP or social agency. Most direct grants and green loans, however, are aimed at owner-occupiers.

A green home loan is a top-up on your existing mortgage at a heavily discounted interest rate (typically 1% p.a. for 3 to 5 years) used for approved energy-efficiency or low-emission upgrades. Kiwibank, ANZ, BNZ and Westpac all offer one. The loan amount, term and approved upgrades vary, so compare carefully.

Yes, indirectly. The Retailer Default Tariff, introduced in 2023, caps the price that retailers can charge customers who have never actively chosen a plan. The Consumer Care Obligations in force since April 2024 also require retailers to identify customers in payment difficulty and offer help before disconnecting.

Yes. The Winter Energy Payment is independent of grants and loans. A typical low-income household can receive a Warmer Kiwi Homes insulation grant, a council top-up, the Winter Energy Payment, and still take out a 1% green loan to add solar or double glazing on top.
