Labour and New Zealand First have signed their coalition agreement, which contains significant policy gains for New Zealand First.
The policy wins for New Zealand First include keeping the age of superannuation at 65, re-establishing a forestry service, and committing to re-entering Pike River Mine.
The deal also contains a strong focus on regional development. The new government will establish a $1bn annual regional development fund, which will include "significant investment" in rail.
The re-established New Zealand Forestry Service will also be based in the regions.

Incoming Prime Minister Jacinda Ardern said the deal represented a huge step change for the government, with regional development and job creation a priority.
"There has been a period of neglect in the last nine years for our regions," she said.
"New Zealand First has brought enormous advocacy at the negotiating table to make sure that we see the beginnings of the re-investment that is much needed in New Zealand."
Other priorities included housing, health, education, the environment and an increase in the minimum wage, Ms Ardern said.
The policies outlined in the agreement fit within Labour's budget responsibility rules it set prior to the election campaign, she said.
New Zealand First leader Winston Peters' campaign push to shift Auckland's port to Northland appears to be on the backburner - the deal contained an agreement simply to look at the feasibility of moving the port elsewhere.
However, the agreement stated that Northland would be given serious consideration in any study.
Mr Peters said he was happy with the deal New Zealand First had made.
"We were never going to get everything we wanted... Politics has been always an issue of compromise, but principles as well, and we have got a balance on both that our team in New Zealand First is entirely happy with, and we're grateful to the Labour Part for understanding that and reaching the agreement we've got."
