Police are asking the public in the Porirua community to be "alert and aware" after a number of women have been indecently assaulted.
Police are concerned about the number of recent incidents in the area surrounding the train station, believed to be linked.
Since February, there have been several reports of women being indecently assaulted while walking around Awatea Street, the Mungavin Avenue underpass and the Kivell Street area.
The most recent assault was reported on August 28 and investigators believe all of these incidents are linked.

"We are asking the public, particularly those on foot alone, to be alert and aware of your surroundings in the area.
"Most importantly if you have information about these incidents, or if you have been a victim of an incident of this nature, we urge you to call us."
Information can be provided to Detective Sergeant Nathan Smith of Kapiti-Mana Police through 105, quoting file number 200829/6042.
Anyone who sees anything suspicious around the area should call 111 immediately.
