If we want assurance that Brenton Tarrant does his time, we need to suck up the cost.
There are calls for the Christchurch mosque gunman to serve his life sentence back home in Australia.
Deputy Prime Minister Winston Peters is calling for the "depraved" mosque gunman to be extradited back to Australia to avoid this country having to pay to keep him locked up for life.
But barrister Philip Morgan QC disagrees, saying there's no guarantee Australia wouldn't release him from prison early.
He told Mike Hosking it's a necessity to keep Tarrant here.
"The cost is ridiculous,  but now he's a serving prisoner, I doubt it will be anything like the millions being bandied about by Corrections."
