Two picnic tables and in-ground lighting has been stolen from Rotokawau Virginia Lake.
Whanganui District Council's Senior Parks Manager Wendy Bainbridge said that the theft of the tables and lighting were in addition to numerous plants taken from the Bason Botanic Gardens in recent weeks, which the ratepayer has to pay to replace.
"The seating, lights and plants are for the enjoyment of everyone in our community and it costs us all when they are stolen," Bainbridge said.
"We are extremely frustrated that this is happening and hope that someone may be able to pass information on to the police that will ensure the perpetrators are caught."
She said it followed increased reports of such thefts from around the country.
