Christchurch mosque attacks: Victims' families disagree with 'rapid and exemplary' police response

Some families of Christchurch mosque attack victims say they disagree with an independent report that found the police response in the 48 hours after the attack to be "rapid and exemplary".

More than 70 recommendations were given to police following the review, which was carried out by a panel including retired NSW Deputy Commissioner Nick Kaldas, Victoria University of Wellington's Jeff Ashford, and former Solicitor General Michael Heron QC.

The report was released on Wednesday - the day after the Royal Commission of Inquiry publicly released its findings into the attack.

Police were on the scene in Christchurch six minutes after the terrorist fired his first shots at Al Noor Mosque on March 15, 2019.

"The report finds that, by international standards, our response was very strong," Police Commissioner Andrew Coster said.

Police say the changes suggested are for "minor improvements", with the main ones around how they interact with victims.

Wasseim Sati, who was shot at Al Noor Mosque, is disappointed, saying his memories of the day are different.

"From me being shot and being helped by one of the public to be transferred to the hospital it has taken some time, and that's where it will need to be looked at again," he said.

Coster said it was "a terrifying situation" for those on the ground.

"We could never get in there fast enough."

The report shows the first reports of gunfire came from the Al Noor Mosque at 1:41pm. By 1:56pm, shots were reported at Linwood Mosque, and at 1:59pm, less than 20 minutes after the murderous journey began, it had been stopped.

Two police officers detained the terrorist just 19 minutes after the first shots were fired. The report found that their teamwork, tactics, and decision making are now considered an example of "exemplary" police work.

Live CCTV footage in Christchurch had allowed the offender to be identified within two minutes via his vehicle registration. But elsewhere, the response moved slowly.

"Just standing on the cordon for six hours, asking police, and the police - obviously it wasn't the usual sort of day for police - were kind of reluctant to say anything," Rosemary Omar, a victim's mother, said.

"Just even being told where to go to find out the information was seriously lacking."

Sati says he hopes the report will encourage change.

"I have no problem with the police department as people, I just want to see changes for New Zealand for a better future for my kids."

Police now plan to release details of the victims' last moments to their families,  which they say will be distressing but families have asked to see it.
