Supporting Families Wairarapa will have to prove to Wairarapa District Health Board that their family support services are a crucial part of mental health and addiction services before funding is restored.
Mental health portfolio manager Simon Phillips said a case needed to be made to determine whether the services were needed.
"It looks like there are people using the service, even though we're not funding them," he said. "[But] I need concrete evidence."
Supporting Families Wairarapa (SFW) lost funding when Wairarapa DHB contracted Pathways and CareNZ to deliver mental health services in 2011.
A report by the Mental Health Commissioner, Dr Lynne Lane, last year found that Wairarapa consumers had less confidence in mental health and addictions services since contract providers had changed.
