He'll keep them guessing and play off one side against the other before, with great fanfare (probably around mid October), he'll announce the winner.
Hell hath no fury like a politician scorned, but that doesn't apply to Bennett as she has no choice but to grimace and bear it.
It has everything to do with a former pal of Peters who was effectively dumped from the Parliament at the election, Richard Prosser.
The MP embarrassed the party in the leadup to the poll by telling businessmen to get rid of their Contact Energy shares, because if his party had anything to do with Government they'd be buying them back but at no more than what they paid for them.
Even though it was the party's policy, Peters distanced himself from the comments and Prosser was relegated from four to number 15 on the list and is now out of Parliament.
It didn't take him long to lose his loyalty, bitching about his former leader, saying it's a myth Peters will consult with his party before deciding on who'll be Prime Minister.
Prosser reckons he'll go left if he can keep the Greens out of his sight - which means out of the Cabinet room. Asked what concessions would Peters make, Prosser scoffed, saying he'll be after the baubles not the policy.
Ouch. But then, for Peters, that'll be like water of a duck's back. He's got bigger fish to fry.
