On Weekday evenings, weekends and public holidays, many bus routes are combined and services are reduced to save costs. Users often end up travelling for longer on the bus, and walking further to or from the bus stop.
The Otago Regional Council tries to get costs as low as possible by frequently tendering Weekday evenings, weekends and public holidays services, and these services often change hands between bus companies. It is quite common for the Weekday evenings, weekends and public holidays service on a particular route to be run by a different bus company to the weekday daytime service. This can be confusing for users.
Your GoCard will work on any bus, no matter which company operates the service.
