The council's acting public transport operations manager Ben Barlow said all 26 bus routes in Hamilton will have air-conditioned buses, with space for wheelchairs and prams.
"This is a key milestone for the BUSIT network. It means people with mobility issues or in a wheelchair, and those with young children in prams, can be certain each Hamilton bus is accessible when they're planning trips."
Gerri Pomeroy from CCS Disability Action Waikato welcomed the move. "We're really excited that all the buses will be wheelchair accessible. It makes journeys better and easier for people with a disability, especially if they don't have independent access to a car."
About 90 buses operate in the city during peak travel times and while a survey of passengers last year revealed 95 per cent were satisfied with their trip, they asked the regional council to improve the ease of travel for wheelchair users and create more wheelchair and pram space on board.
Another survey targeting people who don't travel by bus revealed that 9 per cent of caregivers would use public transport if more pram-friendly buses were available.
The new buses have been built to meet New Zealand's common standard for bus quality, which aims to improve the accessibility, comfort and usability of buses used in urban services.
The requirements for urban standards (RUB) have been developed by the NZ Transport Agency, Bus and Coach Association, public transport operators, bus builders and suppliers, Auckland Transport, Greater Wellington Regional Council and Environment Canterbury.
