It's hoped a dedicated anti-corruption unit will put a stop to growing organised crime, and catch out bent cops.
Outgoing Police Commissioner Mike Bush has announced the new unit - designed to protect against the risk of corruption and investigate the force itself.
Bush told Mike Hosking while corruption remains rare in the New Zealand Police, it does happen.
He says there have been cases where officers have been involved in illicit drug dealing or disclosing information to those involved in crime.
It'll be based at the Wellington National Headquarters, and led by a Detective Superintendent.
