Maori Party co-leader Pita Sharples says he must be at the Cabinet table if ACT leader Don Brash is there.
The Maori Party and ACT have been support parties to the National Party during this term of government.
Dr Sharples says if the Maori Party is involved in post-election talks, it will decide who it will work with after it has talked to its people.
He says if Don Brash does make it back into Parliament, then he must be sitting opposite him.
"If he happens to get through the web and is in Parliament, then I must be opposite him to hold him to account. And, if possible, cut out any of his motions that are anti-good race relations."
At the Maori Party's campaign launch in October, co-leader Tariana Turia said it would decide on bottom lines a week out from the election.
But Dr Sharples says really there are no bottom lines, as the party has made gains over the past three years that were not in its bottom lines following the 2008 election.
The election will be held on Saturday.
