Driver shortages were common at the start of a new year, however this year shortages had been more prevalent because of the current environment where there is greater awareness of the need to socially distance if unwell, she said.
"Go Bus has ensured us that it takes careful consideration of the services that it cancels," she said.
During the past two weeks the Napier to Hastings (12N) and Hastings to Napier( 12H) bus service has regularly had cancellations at peak times, when buses arrive every 20 minutes.
Go Bus, where possible, had been trying to only cancel trips along routes that have more frequent services, she said.
Although multiple services have been cancelled, it's often only because it was one driver short, Brunton said.
The HBRC was working with the Bus and Coach Association to address the shortage.
A new driver recruitment campaign is in the works.
