NSW Deputy Premier John Barilaro is taking mental health leave for up to four weeks after a tumultuous fortnight dominated by koala protection policy.
The outspoken NSW Nationals leader will miss next week's sitting of parliament.
His deputy Paul Toole has been installed acting leader.
Mr Barilaro put himself in the firing line last week when he threatened to implode the coalition government if concessions on the state's koala protection policy were not made.
He backed down after Premier Gladys Berejiklian gave him an ultimatum that Nationals MPs support the government or its ministers be sacked from cabinet.
He survived a no-confidence motion in state parliament on Wednesday despite senior government's minister publicly disparaging his actions.

Ms Berejiklian said she had been advised by the deputy premier he was taking up to a month's leave.
'I have offered him any support he may need. I wish John and his family all the best during this time,' Ms Berejiklian said.
A source close to Mr Barilaro told The Daily Telegraph he was in need of a 'rest'.
'After nine months of helping people rebuild their lives after the worst fires in history, after dealing with farmers who have just faced the worse drought on record and compounded with losing his father a month ago, it's time for a rest,' a source close to Mr Barilaro said.
He was given a standing ovation on Friday morning after telling his party he would continue to fight against the koala policy.
Mr Barilaro said the policy would be the 'nail in the coffin for farmers' and strip them of their land rights.

The Koala Habitat Protection State Environment Planning Policy identified 123 trees that were needed as food or shelter for the animals.
'If we were to support that we would become the laughing stock of regional and rural NSW,' Mr Barilaro earlier said.
'This is the right thing to fight for on behalf of the community.'
More to come.
