The party’s former MP, Hone Harawira, resigned from Parliament last week after launching his new Mana Party.
A by-election will be held on 25 June.
The Maori Party says there is strong interest in contesting the seat.
Names being suggested around Te Tai Tokerau include Ngati Hine leaders Pita Tipene and Waihoroi Shortland, Northland lawyer Mere Mangu and Ngati Whatua chair Naida Glavish.
But the party’s Whangarei co-chair, Solomon Tipene, says so far no-one has confirmed in writing that they will seek selection.
Eligible voters urged to enrol
Meanwhile, Registrar of Electors Stephen Hansen says eligible electors need to be enrolled at their current address by the time the writs close on 25 May to get on the printed roll.
People who sign up after that date would need to cast a special declaration vote on election day.
“It’s important that people check to make sure that the are ready to vote because a lot of people move and we find that we get mail back (marked) gone no address, and we want people to have the opportunity to have their say,” he told Waatea News.
Turn-out in the electorate in the 2008 general election was 63%.
Only electors registered on the Maori electoral roll for the Te Tai Tokerau electorate are able to vote in the by-election.
