The authority's determination means a backbench MP's basic pay rises $7000 or 5 per cent to $141,800, with the increase backdated to July this year.
Meanwhile, in the year to June this year the average wage, according to the quarterly employment survey, rose 4 per cent to $51,100.
Prime Minister John Key, who got an $11,000 pay increase, said that while the 1.5 per cent boost was fair, the lump-sum payment for travel was unnecessary and he was disappointed the Remuneration Authority had awarded it.
Labour leader Phil Goff, whose pay rose by $8700, said his MPs could use the money, but those like himself on high salaries would pay more in tax if Labour won the election.
Mana Party leader Hone Harawira said the pay increase left him feeling "sick in the stomach".
"To accept this pay rise at a time when the poor of New Zealand are in financial strife as a result of the Government's 'take from the poor for the rich' policies is a real kick in the guts for those who are struggling."
Mr Harawira said he would donate his $7200 increase to "one of the many voluntary organisations in my electorate of Te Tai Tokerau trying to help the poor the Government has deserted and I call on all politicians to make a similar gesture".
Meanwhile, the tax-free allowance intended to cover costs including entertaining visitors, donations, gifts and prizes rose 5.3 per cent to $16,100 for most MPs.
