It is also in the wake of an incident where a man fired shots inside the Palmerston North police station in August last year.
Police also announced some volunteer-staffed kiosks in other parts of the country had been temporarily closed and will remain shut until a fuller audit is completed.
The Carterton station is open three hours a day and the Featherston station four hours a day, and this seemed unlikely to change, Ms Howard said.
"Obviously if the review runs through if there are risks identified, there may be some changes but we just have to wait and see what the review comes up with."
Counter staff often dealt with emotional people who wanted answers right away, and it was important to make sure those staff were safe, Ms Howard said.
"People are sometimes quite agitated when they come in and they are not aware of who they are talking to -- they think you work in a police station and they want help -- people can be quite agitated and upset.
"Our counter staff are not always the person they want to see and you never know what people are going to do, so we need to make sure that staff feel safe and secure."
Hours at the Featherston station would be temporarily changed this week due to operational reasons, which were unrelated to the review, Ms Howard said.
Police Assistant Commissioner Allan Boreham said potential security improvements could include issuing staff with safety alarms and adding more security cameras.
"We don't want to make our premises less welcoming to members of our communities but we must do all we can to ensure our staff and members of the public are safe," Mr Boreham said.
