It's been a busy 48 hours for Housing and Infrastructure Minister Chris Bishop as he took big steps toward quickening the progress of large-scale infrastructure projects, with the minister confirming on Wednesday the advisory panel that will provide recommendations on which proposals to fast track.

Then yesterday, Bishop announced changes to tenancy rules that would encourage landlords to re-enter the rental market.

On the infrastructure front, business experts David Tapsell, Rosie Mercer, Vaughan Wilkinson, David Hunt, Mark Davey and Murray Parrish have been hand-selected by the Government to form the committee that will "ensure the process is transparent, and to thoroughly evaluate the suitability of projects".

Bishop was asked on Newstalk ZB this morning whether the committee would be one of the most important big-picture decisions the Government would make.

"I think it's extremely important," he told Mike Hosking.

"One is we'll be substantively able to get some things built quicker in this country, and the second is it sends a message about New Zealand ... that we're open for business, that we want growth, we want to cut through red and green tape and, actually, New Zealand is back."

The advisory group will provide independent recommendations to ministers on projects to be included in the Fast Track Approvals Bill, which would fast-track the consenting processes for particular projects that are considered to have regional or national significance.

The bill was referred to the Environment Committee on March 7 and does not currently contain any specific projects in either schedules. Now project applications – made by either the public or private sectors – can now be made to the Ministry of Environment until May 3.

The newly formed advisory group is said to then evaluate the projects submitted and provide independent recommendations to the ministers of Infrastructure, Regional Development and Transport.

Bishop said his goal was to bring the country into a state of growth and begin building things again at a faster rate.

"[We want to] get out of this malaise we've been in the last few years, where everything is too hard and investors give up, everybody buggers off and says New Zealand is destined for basically middle-income status," he said.

"We can be a high growth economy, with good public services, but that starts with actually building things in this country - roads, rail, infrastructure, renewable energy, mines, agriculture - let's take advantage of our natural resources and let's get on with it."

The second of two announcements made by Bishop was confirmation he would be re-instating the 90-day no-cause terminations for landlords of rentals, a clause that was removed under the previous Government.

Landlords will now also require just 42 days' notice when they want to move into their property.

Bishop told Hosking that while there was no silver bullet to fixing the country's rental crisis outside of fundamental reform, the Government was ensuring Labour's "war on landlords" had ended.

"We'll have more to say on [reforms] in due course, but this will make a difference on the margins for people, it will mean more landlords get back into the rental market," he said.

"Landlords are not the enemy - they're an important part of the rental market, and we need sensible laws that balance the rights of tenants and landlords and this reverts to what it was pre-2020."

The minister told Hosking he'd been given a great deal of feedback from landlords that suggested they wanted to play their part in helping people get off the street - including those with criminal pasts. However, they needed rule changes to make that process easier.

He said many landlords had "a social conscience" and would be prepared to take on those on the fringes of the rental market.

"They don't have that guarantee that if the tenancy doesn't work out, they can't just end the tenancy," said Bishop.

"So we're doing that and we're bringing that interest deductibility as well. So look, I'm not pretending this is gonna be a silver bullet, but I do think it will help, I do think it will make a difference and it's why we're doing it."
