Prime Minister John Key has committed himself to seek agreements again with all three of his support partners - United Future, Act and the Maori Party - irrespective of whether National needs their votes to govern after the election.
"If we are in a position, come November 26, to get around the table irrelevant of how large our party vote is, we are definitely going to make the phone call to these support parties and sit down and have a discussion with them," he said after the United Future conference in Wellington.
Whether that included ministerial posts would depend on the parties themselves.
National entered a confidence and supply agreement with the Maori Party after the last election even though it already had the numbers with Act and United Future to govern.
"It both balanced the Government and gave us greater options and more stability over time."
