Police Commissioner Peter Marshall has apologised for mistakes made during the Urewera raids but says those arrested and convicted should also consider saying sorry for the stress it caused to the community.
The Independent Police Conduct Authority's report released today found in some areas police acted "unlawfully, unjustifiably and unreasonably".
Mr Marshall said he apologised for mistakes but not for the investigation, which focused on alleged military-style training camps in the remote Urewera Forest in the Eastern Bay of Plenty.
The 2007 raids resulted in 18 people being arrested, four of which were left facing charges.
IPCA chairman Sir David Carruthers said the police operation was justified but officers acted "unlawfully, unjustifiably and unreasonably" in establishing road blocks and detaining and searching some people during the raids.
