Re-elected Member for Bathurst Paul Toole has been elected deputy leader of the NSW Nationals.

Mrs Pavey, who was returned as MP last weekend securing 52.6 per cent of primary votes and 65.5 per cent on a two candidate preferred basis, said on Monday that she would be honoured to be deputy leader and consulted with colleagues.

In the vote for the leadership on Friday morning, March 29, Mr Toole defeated Roads Minister Mrs Pavey for the position.

She said it was just one of those things.

"We are told: never be afraid to put your hat in the ring.  I did, and I didn't win, but that's okay.  I just wanted to serve the party, and Paul Toole will be fantastic," said Mrs Pavey.

"I don't anticipate anything else coming up for a while.  I just want to buckle down, and keep serving the party and the people who elected me."

Mr Toole will replace outgoing Water and Primary Industries Minister Niall Blair, who revealed after the NSW election on the weekend that he would be resigning from the ministry and the deputy leader position.

Mr Blair said the abuse he had received about the fish kills in the Murray-Darling Basin had taken a toll on himself and his family.

The vote for the leadership positions in the NSW Nationals was held on Friday morning in Sydney.

It came at the end of a memorable week for Mr Toole, who was comfortably re-elected as Bathurst's local member last Saturday.

Mr Toole received about 56 per cent of the first preference votes and around 67 per cent of two-candidate preferred.

He has been Racing, Lands and Forestry Minister since 2017, but Premier Gladys Berejiklian has yet to reveal the make-up of her new post-election ministry.

As expected, Deputy Premier, John Barilaro has been re-elected NSW Nationals leader unopposed.

Mr Barilaro said he took full responsibility for the election result, which saw the Nationals lose the seats of Murray and Barwon to the Shooters, Fishers and Farmers Party, and the North Coast seat of Lismore to Labor.

"We do accept the weekend's verdict in a couple of those seats [and] that in some areas, and on some policy, we've got to do better," Mr Barilaro said on Friday.

Mr Barilaro said he had heard the message in the far west, and said "regardless of who you elected we are not walking away."

In addition to winning the seats of Murray and Barwon, the Shooters also consolidated their hold on the seat of Orange, which they won by fewer than 100 votes at a 2016 byelection.

The Nationals also came close to losing the seat of Dubbo, after independent Mathew Dickerson fell just short of wiping the 20 per cent margin left by retiring Police Minister Troy Grant.

Mr Barilaro said the Nationals would retain seven seats in the new Coalition cabinet, which Premier Gladys Berejiklian is expected to announce on Sunday.

Upper house MP Sarah Mitchell, who holds the Aboriginal Affairs and Early Childhood Education portfolios, was elected Nationals leader in the Legislative Council.

While the final makeup of the upper house is yet to be determined, the Coalition will likely be forced to negotiate with an expanded crossbench.

Ms Mitchell said was "prepared to work with whoever is elected" to the upper house to pass legislation.
