Wellbeing Budget leak. Or is it hack?

The National Party yesterday released what it said were key details of the government's Wellbeing Budget, due tomorrow. Then yesterday evening Treasury announced it had been deliberately and systematically hacked and the matter had been referred to police. Leader, Simon Bridges says the National Party has not been involved in any computer hacking and the government is "lashing out in a witch hunt". Public law expert Eddie Clark from Victoria University tells us what this means for Labour and National.
