Fares on Bayhopper and Cityride buses are set to rise from Monday 3 August.
The rise, of around five percent to each fare, will see passengers paying for a greater percentage of the cost of running the service.
Schoolhopper fares are not affected by the increase.
Bay of Plenty Regional Council Transport Policy Manager Garry Maloney said the Council had delayed the fare increase as long as it could, which had initially been scheduled for late last year.
