Commenting on his decision to step down, Mr Bowker said: "My time with Tourism Bay of Plenty has been very exciting, seeing how good governance and a strong management team can make a huge difference to this important economic driver for the region.
"Post the Rena grounding this was a time for the organisation to take a look at who we are as a region, and to take a more pragmatic approach to the future of tourism. I'm very proud to say that on all measures I leave knowing that the region is in very good growth, and the new leadership in Ian Smith will see this continue."
Incoming chairman Ian Smith is the owner of the Waihi Beach Top Ten and Beach Haven
Holiday Parks as well as Waihi Beaches' Fire Chief.
Mr Smith said: "As a tourism operator and with a passionate focus on the community - my new role is a good match, and will provide all important continuity to execute on the organisation's ambitions.
As part of the board rotation Lucy Brake, who has served as a Trustee, is also stepping down after seven and a half years.
Rhys Arrowsmith said: "I'd like to sincerely thank the Board (both current and previous) for their support and courage to govern the organisation to make it one of New Zealand's highest performing Regional Tourism Organisations - our future is very bright."
