Mr Davis said Maori electorate MPs, such as Louisa Wall, will continue to be on the list and standing down from the list allowed plenty of places for more Maori to receive high list placings.
"I can see up to 10 Maori MPs in a single party [after the election] which will be an historic first. The aim is to have those 10 MPs as part of the next government so we can make a real difference for our people," he said.
"We approached the party and asked to stay off the list as a show of strength, unity and confidence in our ability to build on the success that we enjoyed at the last election."
He said Labour winning six of the seven Maori electorate seats at the last election was Maori showing that Labour was the preferred political party to address Maori issues.
"The numbers were in our favour and we're looking to improve. Our election strategy is about showing how the Maori Party has failed Maori during nine years of being tethered to National's waka," Mr Davis said.
"We back ourselves to help Maori make progress on the problems they face in housing, health and education. Labour has five Maori MPs in the shadow cabinet and we're all up to prove why we should have the party vote."
Mr Davis said his promise to the electorate was to serve two terms as cabinet minister so he could make a real difference then seek to stand on the list, with a succession plan in place for a strong candidate to take up the Te Tai Tokerau seat.
"Then if I do a good job as a cabinet minister and Te Tai Tokerau MP I'd get a good place on the list. If I don't do a good job I shouldn't deserve a place [on the list] and will be shown the door."
