Parliament handed security guards a power their own peak body refuses to sanction

A power nobody in the industry will use

Parliament passed a law to help stop shoplifters. The industry it was meant to empower is telling its members to ignore it. That is not a slow start, it is a total gap between political intent and operational reality, and it is exactly the kind of gap where employers, insurers and contractors get burned.

A month after expanded citizen’s arrest powers took effect, the New Zealand Security Association, which represents about 85% of the industry, has reported zero arrests by its members. Its advice has not shifted since the law changed. NZSA chief executive Gary Morrison says guards should keep observing and reporting and only conduct an arrest once they have completed appropriate training and certified competency. The badge system that would identify trained guards does not yet exist at scale.

What the law actually changed

The Crimes Amendment Bill passed its final reading on 6 August 2026 and most provisions took effect within a week. Previously the citizen’s arrest defence in section 35 of the Crimes Act only applied between 9pm and 6am, or in daytime for offences carrying at least three years’ imprisonment, so a daytime shoplifting arrest had no cover. The amendment removes those limits and permits reasonable force, including physical or mechanical restraints, to detain someone committing any Crimes Act offence at any hour, provided police are contacted as soon as practicable.

Justice Minister Paul Goldsmith framed it as a promise kept, arguing that situations where people walk out of supermarkets with full trolleys while staff can only escort them to their car could not continue. The frustration is understandable. Retail crime costs New Zealand retailers $2.6 billion a year, and theft-from-retail proceedings hit 8,356 in 2025, the highest in nine years and nearly double the 2022 low.

The liability trap is specific and it is serious

Here is where this stops being a policy debate and becomes a live risk on your books. Detaining someone unlawfully, without consent and intending to confine them, can constitute kidnapping under the Crimes Act, carrying up to 14 years’ imprisonment. The legal defence only holds if the arrest was lawful, the force reasonable, and police contacted promptly. A guard who acts without completed training, or whose employer has no written policy either authorising or prohibiting the power, is exposed to that charge plus civil liability.

The risk runs both ways. AUT Law School Professor Kris Gledhill notes that a person wrongly detained can rely on the same expanded provisions to try to arrest the guard who challenged them, giving a botched detention a legal footing for the offender to resist and claim self-defence. Gledhill also warns of physical dangers police train for and civilians do not, including positional asphyxia that can kill people who cannot breathe properly.

The health and safety collision

Retail NZ flagged the core conflict before the bill passed, telling Parliament that retailers are being granted a power they cannot safely exercise without exposing staff to danger or facing health and safety fines. A retailer who directs staff to detain offenders and sees one injured faces HSWA liability. So does a retailer with no safe system of work for the new powers. Most stores also lack the infrastructure, with few possessing a secure room, continuous CCTV, or amenities such as water and toilets for prolonged detention.

Then there is the escalation risk. In August 2026, Retail NZ chief executive Carolyn Young warned the powers could cause offenders to arm up with a gun, butcher’s knife or machete, citing a real incident where a known offender produced a hammer when confronted.

Police guidance says the opposite of Parliament

The clearest signal comes from the police themselves. Guidance issued on 16 August 2026 tells people not to intervene if it may put anyone in harm’s way, and that in most situations the safest action is to observe and call 111. That is the advice that existed before the law changed. Parliament expanded the authority; police effectively say do not use it.

What businesses must do now

Silence is not a policy, it is unmanaged liability. Any business using guards or running retail premises needs a written policy stating whether staff may use the power, and Young was explicit that retailers must be clear either way. No arrests until training and competency are certified. Insurance cover should be checked against the new risk profile, and any HSWA framework updated. New Zealand is expanding these powers just as the UK, Australia and parts of the US restrict them. The government calls the power optional and leaves it to businesses. That is another way of saying the entire operational and legal risk has been handed to private operators, with no training, infrastructure or funding attached.
