Maori Party co-leader Pita Sharples says he's unhappy with the rise in GST, even though he voted for it.
Dr Sharples says the new 15% rate will hit low-income Maori particularly hard.
But, he told Waatea News, the party had to vote for it as part of its confidence and supply agreement with the Government.
The goods and services tax was originally introduced on 1 October 1986 at 10%. Income tax rates were lowered at the same time.
GST was raised to 12.5% on 1 July 1989.
