The police response in the first 48 hours following the Christchurch mosque attacks has been deemed excellent, but a new report still makes more than 75 recommendations for improvements.
The release of the independent review follows the Royal Commission's report yesterday into the mass shootings that killed 51 people.
Operation Deans - the official debrief of the police response - applauds the "exemplary" leadership shown by Canterbury and police national headquarters, pointing to the arrest of the murderer within 20 minutes of the first shots being fired.
The country's top cop at the time, Mike Bush, gave a public statement on the attacks at 5:29pm.
Today's report also highlights areas that need work.
There weren't enough family liaison officers to help after the shootings. The 111 system doesn't routinely accept texts - critical for victims who are in hiding. Poor communication around victim identification and the release of the bodies to whanau escalated tensions.
There were delays recognising police staff were traumatised after seeing the live video feed of the mass killings. And local police commanders were unaware of an advanced sniper training exercise in Christchurch on the day of the attacks, and some specialised staff involved in that were armed and deployed themselves to the incident - but were not carrying recognisable identification.
