Maori Party co-leader Te Ururoa Flavell says there is no political will to reduce Maori electorate boundaries, to improve tangata whenua representation.
The Representation Commission has proposed no changes to the boundaries of the seven Maori electorates, because they are within their population quota.
Mr Flavell says it does not address the ''ridiculous'' situation that the Tai Tonga MP is expected to represent over half of the land area of Aotearoa, which spans 18 general electorates.
He says the size of the Maori electorates is a major problem it has discussed with the Electoral Commission and MPs, but says there is no political will to change it.
Mr Flavell says electoral law guarantees there will be at least 16 general electorates in the South Island so each one won't be too big, and that approach should apply to Maori electorates.
