The ballot box closes at noon on Wednesday for Ngapuhi people voting on a mandate process to settle Treaty of Waitangi claims.
The Tai Tokerau hui have been tense at times, with fierce exchanges between Tuhoronuku chair Sonny Tau, opponents of direct negotiations and their lawyers.
A number of hapu, including the biggest sub-tribe Ngati Hine, have asked the Waitangi Tribunal or the Maori Land court to intervene, saying Tuhoronuku does not fairly represent them.
Tuhoronuku sources say the board will see how the voting has gone before it decides whether to apply to the Crown to recognise its mandate – and it is open to talks with dissenting hapu.
The voting has been handled by a Christchurch firm and it says registrations will need to be verified before the votes can be counted – a process that could take a couple of weeks.
