Bill English has revealed the roles his MPs will hold as National "pushes the button on Opposition" - saying the party will use its size to frustrate progress for the new Government.
Parliament resumes next week and English today announced the portfolios he has assigned to his team, including a big promotion for Judith Collins.
"You should expect more tension and more pressure in the Parliament, and particularly through the select committee process. Because we are the dominant select committee party," English said.
"And that is going to make a difference to how everything runs - it's not our job to make this place run for an incoming Government that is a minority.
"You will get to understand that it is a minority Government with a majority Opposition, and the Greens as the support party. That is how we are going to run it...we have no obligation to smooth [Labour's] path. None whatsoever."
Labour and NZ First Coalition have 55 votes combined, compared with National's 56. However, when the Green Party - supporting the Government on confidence and supply - is added there is a clear majority.
English attacked the Labour-led Government on a number of fronts, labelling its thinking on social policy "pre-internet" and saying current employment and construction figures would be a benchmark of success.
"If this is poor performance then all they have to do is exceed it."
The major portfolios have largely been assigned to their former ministers, including Finance to Steven Joyce, Education to Nikki Kaye, Health to Jonathan Coleman, and Justice to Amy Adams.
Waimakariri MP Matt Doocey will hold the newly-created position of spokesman for Mental Health. Doocey worked in mental healthcare management before entering Parliament in 2014.
Major changes include Judith Collins picking up Transport, previously held by Simon Bridges. Bridges picks up the crucial task of being spokesman on Immigration, and also Economic and Regional Development and Immigration.
English said Collins had performed very well since getting back into Cabinet.
"I think Phil Twyford will find her way of doing business suits Opposition."
Amy Adams drops Housing, which is picked up by Michael Woodhouse, who also gets Social Housing. In return Adams gets Woodhouse's old portfolio of Workplace Relations and Safety, including Pike River.
English said he wanted Adams and her "crystal clear legal mind" in Workplace Relations.
"It is probably one of the most concerning of the Government's economic policies - a reversion to pre-1990 industrial relations models."
Louise Upston has picked up Social Development from Anne Tolley. Simon O'Connor picks up Corrections, which was held by Upston.
Nick Smith no longer has Environment or Building and Construction. He now holds Forestry and Aquaculture. Scott Simpson, who was the former Environment Minister, is now National's spokesman in that portfolio.
English said Smith had done a great job in housing, despite the criticism he got in that role.
"He and I would both be of the view it is time to move to something else," English said, adding he thinks Smith will see out the term.
There are big promotions for Chris Bishop, picking up Police and Youth, and Todd Muller, who gets Climate Change and Crown/Maori Relations.
Treaty Negotiations and Maori Development have gone to Nuk Korako.
English will be spokesman for National Security, while deputy leader Paula Bennett will hold Children, Women and Social Investment. Joyce holds Finance and Infrastructure, with Gerry Brownlee spokesman for Foreign Affairs, Fisheries, and Land Information.
He said he didn't know how many of his MPs planned to leave Parliament over the next term, saying those decisions were theirs to make, but none had indicated plans to leave.
"All I can say is I have been impressed by the enthusiasm of our MPs who have the choice to leave to stay."
