Labour leader Phil Goff has ruled out a deal with Te Tai Tokerau MP Hone Harawira or any party he leads.
''I don't believe he would be a suitable coalition partner,'' Goff said.
He said Harawira was not reliable and had expressed some extreme policies that Goff found personally offensive.
"I don't believe you could form a stable government on a relationship with Hone Harawira."
However Goff continued to leave the door open to NZ First led by Winston Peters, saying he would wait to see if Peters made it back into Parliament.
He said Peters had stuck with a Labour Government for three years and as Minister of Foreign Affairs he had acted in a way that was compatible with the support agreement.
There would be a bottom line in any deal with NZ First.
"I have not made a decision with respect to Winston Peters because it would be hypothetical."
