Abuse and Rape Crisis Support Manawatu is reducing its counselling hours after government funding cuts.
ARCS manager Ann Kent said the group was now relying on public donations while continuing to apply for public grants.
ARCS needs $25,000 to maintain its services for this financial year. The organisation has not received any funding for its education programme, which may be the first to go if funds aren't found.
"We are working to prevent sexual abuse, particularly by working in high schools focusing on having healthy relationships. These prevention education programmes will probably be the first service to be cut," Ms Kent said.
She said that Manawatu needed ARCS to provide a specialist service to locals who had been abused.
