Whanganui's Tranzit buses had nearly double the usual number of passengers last week.
During the second week of the school holidays, October 6-12, all the buses were free, Horizons Regional Council transport manager Phil Hindrup said.
Horizons has also introduced new bus timetables, with more evening and weekend services, and made a slight change to the Aramoho Orange service.
In March this year bus use was declining across all users, including gold card holders. Horizons reviewed it and formed a bus advisory group. The new services are the result.
Free travel was a great attraction, with numbers last week up 81 per cent on the week before. Hindrup heard reports of families trying out the buses for the first time.
