Transport Minister Dean Nalder has survived a crisis meeting with Premier Colin Barnett, retaining his Cabinet position and pledging his full support for Mr Barnett's leadership.

After a meeting lasting 90 minutes, Mr Nalder emerged from the offices of Premier and Cabinet to deliver a measured and carefully-worded account of the discussion.

"I regret that the public commentary has forced me to have a meeting like this with the Premier," he said.

"I fully support the Premier."

Mr Nalder was summoned to the meeting in the wake of an opinion poll, which was paid for by a group of prominent Perth business figures and showed the Government was set to lose next year's election.

Mr Barnett had refused to guarantee Mr Nalder's future as a minister on Thursday.

Following Friday's meeting, Mr Nalder said his focus and commitment would now be on being the Minister for Transport and the Minister for Agriculture.

Mr Nalder was quizzed on which aspects of the "commentary" he regretted.

"I regret all the noise involving me that's occurred in the last 72 hours," he said.

"I don't think that's good for the Liberal Party and the Government. I came to Parliament and am committed to doing the best I can for Western Australia and [I] will always do that."

Barnett releases brief statement

Mr Nalder was also asked if he felt those who had commissioned the poll had placed him in a predicament with the Premier.

"Look, I'm not doing to get into anything further other than to say I've had the discussions with the Premier. We talked it through," he said.

"Any further discussions need to be raised with the Premier directly."

Mr Barnett declined to comment on the specifics of the meeting, releasing only a brief statement to the media.

"We discussed the issues in detail. I have no further comment," he said.

Earlier, senior Liberal Minister John Day said Mr Nalder needed to overcome his political naïveté and express clear and unwavering support for Mr Barnett.

Mr Day suggested Mr Nalder's ambiguous public statements had fuelled ongoing speculation about his role and intentions.

"I think Dean has been somewhat naive in some of the discussions he has been involved in," Mr Day said.

"The best thing that Dean can do is go out and make it very clear publicly that he wants stable and predictable government in Western Australia, that he wants to play a part in that under Colin Barnett's direction and leadership," he said.

"Dean has got a strong future if he establishes a firm foundation."
