It was due to operational requirements, Ms Turia said.
"But the station has still been operating, with staff deploying from there, and on most occasions there would still be someone inside the station managing our custody area."
Eastern Police District communications manager Kris McGehan said very few people went to a police station at night.
"The station doesn't close - it is just the front counter," she said.
The counter would remain manned during the day.
Occasional night closures would not affect the Hastings Police Station, where staffing levels were higher.
Ms Kura said automatic phones were being installed at the front of the station for the public to use to ring police directly to report a crime or get personal assistance - "exactly the same as they would from their homes".
She said the service provided at the public counter was no different to when someone rang police directly.
"If a member of the public comes to a station and the public counter is closed they should ring the normal Hawke's Bay police number of (06) 831 0700 or in the event of an emergency they should ring 111."
Ms Kura said it was important for the public to realise that policing was a 24-hour service "and with the benefits of increased use of technology and managing our deployment to where the demand is we can be more accessible to the community".
The man who spotted the darkened foyer said the public needed to be aware of the situation, and while he could see the police point of view he felt it was always more reassuring to see lights on in the front of a police station.
