It's hypocritical of National to pay a third of Beehive staff more than $100,000 while the rest of the country has to tighten its belt, Labour says.
Figures released to Fairfax NZ show a third of Ministerial Services staff working in ministers' offices earn more than $100,000 a year while the average salary is $93,298 - an increase of 5 percent on the year before.
Labour's State Services spokesman Kris Faafoi says National's hypocrisy is "rank".
"At a time it's telling teachers, nurses and our front line police officers not to expect large pay increases, National is paying more of their staff six figure salaries," he said.
"This shows the lie of National's promise to keep costs down. National's wasteful spending on hair-straighteners, over-priced signs and business-class flights has now extended to its own staff."
Taxpayers' Union Executive Director Jordan Williams said it was "extraordinary" that ministers were paying so well.
Backbench MPs are paid $150,047, while Cabinet ministers take home $272,581.
