Two men reportedly use crowbar to get in to Northland Woolworths

Police are investigating a break in at a Northland Woolworths supermarket early on Saturday morning.

Officers were called to Dargaville's Woolworths on Victoria Street at about 5:30am.

"Reportedly two men used a crowbar to gain entry through the store's front entrance. An investigation is in progress," police said.

Woolworths spokesperson Robin Pinner said the store was working with police and had provided CCTV footage of the incident and those involved.

Pinner said the store was open and trading on Saturday with no impact on customers.

"Unfortunately, we continue to see retail crime have a very real impact in our stores, on our team, security guards and customers, and their whānau, despite extensive security measures and efforts individually and working across industry.

"Our team deserve to come to work and feel safe, and to go home safely to their whānau."
