Prime Minister John Key says no final decision has been made about who will lead a United Nations inquiry into Israel's boarding of an aid flotilla in Gaza.
Former Prime Minister Geoffrey Palmer has been suggested as the person who will chair the independent inquiry into the incident, in which nine people were killed.
The ship the activists were on was seized by Israeli commandos in international waters, to maintain Israel's blockade of Gaza.
Mr Key says the UN is still working with the parties involved, including Israel and Turkey.
He says terms of reference have not yet been set and no names have been formally announced.
