For the last week people have been receiving scam phone calls asking them to donate to Whanganui's Bushy Park Sanctuary.
Bushy Park chairwoman Liz Tennet has heard about three of the calls, and is concerned.
She said Whanganui Police have been informed.
The caller says the forest sanctuary needs money for all sorts of different reasons. One plea was for money to start a creche for young kiwi.
"That's definitely not something that we're doing," Ms Tennet said.
