The Mana Party has outlined its draft policies, including higher taxes on fast-food chains and the rich.
Co-vice-president John Minto says the tax system is heavily skewed towards making a small number of people extremely wealthy.
The party also wants to make Maori language learning compulsory in schools.
The party wants to abolish GST and offer a much broader capital gains tax than Labour, which wants a flat 15% tax.
It will also push for the establishment of a Treaty of Waitangi Commission, independent from the Crown, to oversee recommendations made by the Waitangi Tribunal.
