Rt Hon JACINDA ARDERN: Again, very crude analysis here. If you divide the cost of spending and there are fewer prisoners, then the cost per prisoner goes up. If the member wants to achieve economies of scale in corrections by having more people in prison, that explains why that Government when they were in office started building a mega prison. When we came into office we said that is not the kind of style of corrections service New Zealanders want. There will not be American-style mega prisons on our watch. We will also not invest in rehabilitation programmes that are sometimes eight hours long and call it a success. We've invested in programmes that work and that reduce reoffending and—proof is in the pudding—reduce the number of people in prison.
