"There's a lot of paranormal 'hotspots' in Wanganui - for example, the cenotaph. A lot of people have seen unexplained figures walking around there."
Mr Sturmey said the group members always tried to "debunk" the strange images on photos or odd noises in recordings that they'd captured, but couldn't always do so.
He said many people seemed to believe in paranormal phenomenon. "There's a lot of interest in what we're doing, and so many people have experienced spirits or ghosts or other paranormal activity."
Mr Sturmey said Wanganui Paranormal Investigations is available to investigate if someone thinks their house has paranormal activity in it.
The group can be contacted through its website, www.wanganuiparanormalinvestigations.com.
