The Government is to spend $100 million over three years on insulating more cold homes.
The programme called Warm Up New Zealand: Healthy Homes will target low-income households, especially families with children and high health needs.
It follows an earlier programme the Government says will have insulated 230,000 homes by the time it ends in September 2013.
The new programme is expected to insulate another 46,000.
Energy and Resources Minister Simon Bridges says the Government's investment in the programme will be matched by significant levels of funding from trusts and other third parties.
The programme will be delivered through the Energy Efficiency and Conservation Authority, with details announced in coming weeks.
