Armed units to patrol in three areas starting on October 28 on six-month trial in response to mosque attacks in March.

New Zealand officials said on Friday that armed police will patrol parts of the country in a trial project amid heightened security concerns after the mass shooting in Christchurch in March that killed 51 people.

New Zealand, like the United Kingdom and Norway, is one of the few countries in the world where police do not carry guns while on general duty. However, hand guns, rifles and tasers are kept in their vehicles and can be used with a supervisor’s permission.

Serious crime is relatively unusual in New Zealand, although front-line police were armed for several weeks following the mass shootings at two mosques in Christchurch on March 15 by a suspected white supremacist.

The attack sparked a debate on whether all police should carry fire arms.

“Following the events of March 15 in Christchurch, our operating environment has changed,” Police Commissioner Mike Bush said in a statement on Friday.

“Police must ensure our people are equipped and enabled to perform their roles safely and to ensure our communities are, and feel, safe. This means having the right people with the right tools, skills and knowledge ready to respond at all times,” he said.

The Armed Response Teams will be deployed in Manukau county in Auckland, New Zealand’s largest city, and Waikato and Canterbury on October 28 on a six-month trial.

They will be routinely armed, equipped, mobile and ready to support front-line police officers at incidents that require enhanced tactical capabilities, Bush said.

He said there was no immediate threat.

1.5 million guns

Australian national Brenton Tarrant has been charged over the Christchurch attack, New Zealand’s worst peacetime shooting. Tarrant has pleaded not guilty to 92 charges against him and faces trial in May.

Threat levels have been heightened around the country since the mass shooting and 1,400 firearms have been seized from offenders since March.

Police Minister Stuart Nash said the move did not mean that police would be armed routinely.

“The three areas have been selected for the trial because of the incidence of crimes involving armed offenders,” Nash said.

“Police turn up to some call-outs with no knowledge of what they are walking into. Every month police turn up to 200 incidents where a firearm is involved,” he said.

Nash was also quoted by the New Zealand Herald as saying previously that he does not support the general arming of police.

New Zealanders must have a gun licence to own a firearm. There are an estimated 1.5 million guns in the country.

The government banned military-style semi-automatic and other high-calibre guns within weeks of the Christchurch shooting and also introduced a gun amnesty scheme.

More than 29,000 firearms have been collected so far, according to statistics provided on the police website.
