Finance Minister Bill English says the Australian and New Zealand governments are to exchange ideas on private sector involvement in infrastructure projects.
Mr English has returned from a day of meetings with Australian ministers.
He says Australia has a depth of experience in getting private participation in big infrastructure projects, and officials from both countries will share ideas.
Mr English says Australia is also trying to clean out the regulations that block business confidence and investment in infrastructure, and has a lot of good ideas that New Zealand can harvest.
He says Australia and New Zealand already have one of the closest economic relationships of any two countries in the world.
