Rhys Arrowsmith will be stepping down in mid-2016 after four years as general manager of Tourism Bay of Plenty.
Mr Arrowsmith, 47, had given a "generous" period to allow the board and team plenty of time to recruit an appropriate replacement, as well as providing due notice for the number of tourism-related national and regional roles he holds, said Tourism Bay of Plenty chairman Ian Smith.
Mr Arrowsmith is currently a trustee of Regional Tourism Organisations of New Zealand, a board member of Cruise New Zealand, and has recently resigned as chairman of regional tourism collective Explore Central North Island.
"Rhys has helped build a strong, highly capable and passionate team and this has evidenced itself in the latest visitor results just out," said Mr Smith. "We are very grateful for the leadership he has shown and wish him only the best for his next role - whatever that may be."
Recruitment for his successor will begin early next year.
