NZ First Winston Peters has taken no time getting one over Prime Minister John Key in the handyman stakes.

Key admitted, after a video of him repeatedly missing a nail he was trying to hit, that wife "Bronagh gets a man in" for jobs around the house.

Peters on Wednesday tweeted "No nail fail here. This is how a real Kiwi bloke handles a hammer" with a video of him hitting it every time – and taking a spare nail out of his mouth in true toolman style.
