Sam Broughton will take a 10 per cent pay cut for the first six months of the coming financial year, the Selwyn District Council said.
It will see his salary reduced from $136,500 to $129,675.
The cut was determined independently by the Remuneration Authority following a law change in May to allow it to reduce mayoral salaries.
The change allows the authority to reduce salaries by up to 20 per cent for six months.
In a letter to mayors, authority chairwoman Fran Wilde said the pay cut would only apply to elected members who earn more than $100,000 a year.
Broughton said he welcomes the cut.
“It is important to me that I am able to play my part in making savings for the district in this way, and I am grateful that the Remuneration Authority has recognised my desire and that of other mayors around New Zealand to help out by reducing our wages.”
The law change does not apply to district council staff.
However, district council chief executive David Ward has previously confirmed he will take a 15 per cent per cent pay cut for the next year.
Christchurch Mayor Lianne Dalziel will also have her pay cut by 15 per cent, meaning her annual salary will fall $14,625 from $195,000 to $180,375. Christchurch City Council chief executive Dawn Baxendale will take a 10 per cent cut in her salary for the full 2020/21 financial year.
