Changes have been made to the way prisoners are managed at several Bay of Plenty police stations after a man died in police custody in Rotorua.
Rotorua coroner Wallace Bain has found that Anthony McGuire, 33, took his own life in May 2008.
Police say a full and thorough investigation was carried out into the death and the management of Mr McGuire in custody.
Rotorua area commander Inspector Bruce Horne says police acknowledge there were lapses in their procedures.
He says some changes came about through the opening of a new custodial facility at the Rotorua station two months after Mr McGuire died. There is now a greater level of supervision and staffing, he says.
A spokesperson for police national headquarters says the police have had robust guidelines and policies for the custodial management of prisoners since 2005.
The spokesperson says they are regularly reviewed and updated and a new policy update is currently out for consultation.
