The Police watchdog report finds three Wellington officers acted justifiably in self defence against a man in Khandallah this year

The IPCA investigated a Police family harm callout - where a man with a large knife was chasing a woman and a baby in the street.

The offender was tasered twice by two officers - after a first tasering was ineffective.

The man fell and hit his head on the road.

The report finds Police gave the man appropriate care before he was taken to hospital.

Police accept the reports findings and say it stopped a dangerous situation evolving into something much worse.
