Under the incentive scheme, which will pay 60 cents for each additional passenger fare above the numbers carried the previous year, the bus company would need to increase passenger levels by about 12 per cent from current numbers to qualify for the full bonus in the second year of the new contract.
Go Bus commercial director Craig Worth said incentive conditions were not unusual in these types of contracts for public bus services. Passenger numbers on the Hawke's Bay bus services have grown strongly over recent years, although they dipped last year after reaching a high in the 2013-14 year. The council has said recent falling petrol prices are one factor encouraging commuters back off the buses and into private cars.
Mr Worth said reliability was a key to maintaining patronage.
"If the bus is generally pretty reliable every day, passengers have confidence in it," he said.
Asked if Go Bus would bid to renew its contract in Hawke's Bay, Mr Worth said the company was pleased with what it had achieved under the present contract and would be reviewing the tender documents as a first step.
The council said in the tender documents "substantial improvements" had been made to the service since the contract was last tendered in 2009. It was open to tenderers submitting alternative proposals that provided a more efficient, economic, or higher quality service.
