Metro Cammell Weymann
For the expanded network, 10 Crossley Empires were purchased in 1949. These were followed by BUT RETB/1s bodied by Commonwealth Engineering (38), Metro Cammell Weymann (52) and New Zealand Motor Bodies (19) between 1951 and 1964, the last 38 chassis being manufactured under subcontract by Scammell. Sixty-eight Hawke Coachwork and Coachwork International Volvo B58s were delivered between 1981 and 1986, with 20 unused New Zealand Motor Bodies bodied Volvo B10Ms purchased from the Auckland Regional Authority after it cancelled plans to renew its network. The B10Ms were later converted to diesel buses.
