Melissa Haines: Bunnings NZ manager on the rollout of new facial recognition technology - Heather du Plessis-Allan Drive

Repeat offenders are the target of the recent Bunnings facial recognition technology rollout.

It's turning on scanners in Te Rapa and Hamilton South today, before later rolling them out countrywide.

Threats have more than doubled in the hardware retailer's stores in the past four years, 34 percent from repeat offenders.

Bunnings New Zealand general manager Melissa Haines says data on regular shoppers won't be kept.

"If someone comes into our stores, there's a very quick scan of the face - if there's any match to a person that's previously committed serious harm in our stores, then that's where we're using it."
