Ngapuhi factions say Prime Minister John Key used his Waitangi Day speech as a platform to prematurely force a historic settlement with Ngapuhi in election year for political gain.
In his speech yesterday, Mr Key held out the prospect of an advance payment against the eventual settlement for New Zealand's largest iwi.
He challenged Ngapuhi to put aside its differences to enable that and said he was keen to see a deal struck this year.
He noted other iwi had previously received similar advance payments.
