Labour's Napier candidate and Minister of Police Stuart Nash says prison numbers have dropped "because there are far too many people in prison that shouldn't be in prison".
In this Local Focus video, Nash is one of five candidates giving a wide range of opinions on New Zealand's prison system - from locking up all inmates to finding better ways to rehabilitate them.
National candidate Katie Nimon says too many offenders are seeking a life in prison, rather than in society. National has "some strong views" that had been given a lot of thought.
"It's a collaborative approach," she said. "We are all New Zealanders and whether we are represented by a National government or not, it takes a lot of smart thinking to come up with some solutions to these things."
