By-election nominations close on Tuesday, giving candidates the summer holiday period to campaign.

Hoff-Nielsen said it should be up to Māori to decide, rather than those on the general electoral role, and that Māori wards were a "no brainer."

By-election voting begins on January 26, closing on February 17.
