Welfare payments could hinge on enrolling to vote, if the Labour Party gets its way.

It says New Zealand should follow other countries and make enrolment a pre-condition of state support - like benefits or state housing.

Labour's made the suggestion in its submission to a judge's review of voter enrolment and turnout issues in Te Tai Tokerau.

Party general secretary Tim Barnett also believes people aren't enrolling to avoid their address becoming publicly available - including to debt collectors.

He says more people should be able to join the private electoral roll.
