Whanganui District Council is urging visitors to Aramoho Cemetery to lock their vehicles after several thefts were reported.
The council's general manager of property and open spaces, Sarah O'Hagan, said it was disappointing to learn that cemetery visitors had been targeted.
"Recently, a number of people have told cemetery staff about incidents of theft when visiting the Aramoho Cemetery," O'Hagan said.
"Our understanding is that these have ranged from thefts of valuables from cars to bag snatches."
She said council staff working at the cemetery take real pride in maintaining and providing a peaceful space where people can spend time visiting their loved ones.
