Whangarei Police Acting Sergeant Hayden Spence commended the owners of Split Bar for noticing the suspicious behaviour and letting police know.
"It's pretty good work from them, it certainly helps us when people let us know about suspicious behaviour because we can't be everywhere at once. They made the right decision to come back and check [the business]." Police said a 13-year-old girl and a 14-year-old girl have since been referred to Youth Aid, and a 17-year-old female was due to appear in the Whangarei District Court yesterday on a charge of burglary.
Northland representative for Hospitality NZ Phil Sentch said the owners' actions were good for business across town.
"We don't want these issues in town because when we have them, people don't come out and we lose business," Mr Sentch said.
He said the owners of Split Bar were young, smart and ran their business well. "You often hear of these so-called smash-and-grabs in back areas of bars where it's dark, poorly lit and with easy access," he said.
Bottles of alcohol were easy to transport, and easy to sell, he said.
"For anyone to pinch anything it can cost us a lot and it takes a long time to start making profit again."
Sabai Thai on Bank St, Whangarei was recently burgled by thieves also looking for alcohol and police are making inquiries as to whether the teenage girls were involved in any other burglaries.
Northland police said it was important that people report suspicious behaviour to police, who are putting a priority on burglary offences.
