Aims Psychiatrists (n=26) and mental health nurses (n=18) engaged in the practice ofpsychotherapy were surveyed regarding their perceptions and engagement in professional development activities. Methods Collaborative Research Network’s (CRN) methodology was followed, and comparisons with CRN samples from Canada and the United States of America(USA) were undertaken. Results New Zealand psychiatrists reported perceived development across their careers, but their ratings were lower than those of nurses. Both professional groups rated their overall development lower their Canadian counterparts. However, New Zealand nurses reported more involvement in supervision than psychiatrists, and both groups reported rates that exceeded those reported in Canadian and USA samples. New Zealand subgroups reported low involvement in personal therapy in comparison to overseas samples. Supervision and personal therapy were highly regarded by New Zealand practitioners, but didactic training was rated as less important. Conclusions: New Zealand mental health professionals reported attainment of therapeutic mastery and skill acquisition. New Zealand psychiatrists reported less involvement in case supervision, but rated supervision as having the greatest influence to their development. The results highlight areas of need for continuing professional development for these professions.
