A bank in Paraparaumu was held up near closing time on Friday by a robber police believe was wielding a gun.
Police said the man went into the ASB Bank at Coastlands mall at about 4:30pm on Friday, threatened staff and presented what appeared to be a firearm.
"No shots were fired and no one was injured during this incident, although staff were understandably shaken," police said in a statement.
The man took off with an undisclosed sum of money, fleeing the scene on foot.
The bank is located on the outer perimeter of the mall, next to a main entrance. Police want to speak to anyone who was in the area at the time and saw the man leaving.
