Pay-fixing system gives parliamentarians vested interest in widening inequality, says party co-leader.
The Greens will push for legislation to lock MPs' and ministers' pay rises or even cuts to the same dollar amounts ordinary New Zealanders receive.
Co-leader Russel Norman said his party would seek a law change to ensure "that MPs' salaries are part of the solution to rising inequality, rather than part of the problem".
Last year, MPs' base salary rose 2.2 per cent or almost $3000 a year while the median income rose by just $780.
But Dr Norman said the independent Remuneration Authority was effectively obliged under current law to link MPs' pay to that of top earners.
