Waikato-Tainui and Ngai Tahu have received top-ups on their Treaty of Waitangi settlements reaching $370 million, the Government has confirmed.
The payouts, made in December, saw Ngai Tahu receive $180 million and Waikato-Tainui $190 million, according to Fairfax.
The top-up was triggered by an old "relativity clause" in the original 1994 treaty contracts which said once total iwi settlements reached $1 billion, both tribes would be entitled to a percentage of all future settlements.
Ngai Tahu would be entitled to 16.1 per cent and Waikato-Tainui to 17 per cent of all future settlements to other iwi, in 1994 dollars.
December's respective payouts are more than either iwi originally received.
