Police are not investigating after a man brazenly walked out of an Auckland grocery store with a trolley full of goods without paying for them.

But the supermarket says it is using its own security measures to detect and prevent shoplifting.

Last Thursday, a man in his 20s strolled out of a Countdown store in Meadowbank with a trolley crammed full of groceries. When he was stopped by staff who asked for payment he replied that was not going to happen.

A Countdown spokesperson confirmed police were not called but said the supermarket chain had a number of security measures to detect and prevent such criminal acts.

Retail NZ chief executive Greg Harford said general advice to all retailers was to report any criminal activity they spotted to police.

Greg Harford joined Simon Barnett and James Daniels.
