The Warmer Kiwi Homes programme in New Zealand, launched in its current form in 2018, provides grants that cover 80% of the cost of insulation and clean heating for low-income households. New Zealand’s Energy Efficiency and Conservation Authority (EECA) administers the programme. Qualifying homes must be owner-occupied, built before 2008, and either be situated in an area that is classified as low-income or have one occupant that is a holder of a Community Services Card. EECA maintains a list of approved energy products and a panel of registered energy service providers that deliver the measures and conduct regular and random audits. Total funding allocated to the programme over four years was originally NZD 142.5 million (EUR 85 million) for the insulation or installation of heaters in 52 000 homes. The programme has since received an additional NZD 176 million in funding to retrofit an additional 50 000 homes by mid-2023.
