Twelve people travelling as part of a group of 48 Italian tourists staying at a Jerusalem marae on Sunday night had $5000 worth of gear taken by thieves.
The group were attending a dinner about 7pm when the thieves snuck into the area where personal belongings were stored.
Raetihi Constable Bernie Deadman said the marae visit was part of the tourists' trip down the Whanganui River.
They left Wanganui for Wellington yesterday and were upset.
Mr Deadman said the crime was extremely disrespectful, not only to the victims but also to the Jerusalem community.
