Baypark original caterer Colin Davis has followed speedway promoter Willie Kay and is finishing up at Baypark Stadium late next month.
Tauranga City Venues Ltd (TCVL), which manages the facilities, wanted to take catering in-house and establish its own team to look after the food service for the stadium, conference centre and the new TECT Arena at Baypark, which includes a cafe.
Baypark general manager Ervin McSweeney said: "We wanted to control all aspects of the service, and get the pricing and quality levels to where it should be.
"Colin has provided long and loyal service to the venue and done a very good job, but under an independent contract you get what you are given," Mr McSweeney said.
Mr Davis, who operates Onsite Group, has been Baypark's only caterer for the past 10 years. His last event will be the ITM Cup rugby match between Bay of Plenty Steamers and Canterbury on August 23.
