Labour leader David Shearer won't rule out supporting Winston Peters' policy of buying back Mighty River Power shares at cost if they form the next Government.
Mr Peters said he would be happy for a Government of which he was a part to borrow or to use the superannuation fund to buy back shares at no more than cost.
Mr Peters said his NZ First party was renowned for going into negotiations "knowing what we want and getting what we want".
"Borrowing money would make economic sense because the returns would make that totally feasible, but there are other resources," he said.
"You've got the superannuation fund, KiwiSaver or a number of avenues or options you could exercise."
