Bay of Plenty District Health Board director of nursing Julie Robinson said other notable outcomes included staff satisfaction increased, staff turnover decreased and a reduction in patient falls.
"The benefits are both tangible and intangible, some of the things are really hard to measure for the dollar value but staff who can come to work and do the job they believe they are employed to do which is to be with patients," she said.
"That return on your investment and for your staff is certainly well worthwhile putting the programme in."
All 10 wards at Tauranga Hospital and one ward at Whakatane Hospital have now fully implemented the programme - which consists of three foundation modules and eight process modules - over the course of the last five years.
Over 625 staff have been trained in Releasing Time to Care and Tauranga Hospital's Mental Health Unit plans to begin implementing The Productive Mental Health Ward this year.
