The biggest investment at Hawke's Bay Hospital since the amalgamation of Napier and Hastings hospitals in 1991 was officially opened by Health Minister Jonathan Coleman yesterday.
The $22 million mental health inpatient unit, Nga Rau Rakau, has 23 beds and includes a gym.
It was co-designed with a Patient Advisory Group which started as a stakeholder group that the Hawke's Bay District Health Board consulted with, but evolved into a partner.
Director of area mental health services Simon Shaw said the co-design was "one of the greatest success stories of this project".
"One of the clearest messages from the consumer group was that people wanted easily-contactable and culturally accessible services which would respond quickly, preventing most people from needing hospital," he said.
