It could be fitted with a body with a maximum length of 27ft . The engine was a front mounted Perkins P6 The Mk 6, introduced in 1950, was simply a lengthened version of the Mk 4, with an overall chassis length of 25ft 11in on a wheelbase of 16ft 4in (5m) designed for a maximum body length of 30ft, the mechanical specification being unchanged.

The North Shore Transport Co Ltd

Takapuna. 1 Mk6/1 buses with own B34F body. In PSV circle 1961 8 buses, numbers 8, 9, 23, 24, 77-80 are described as Mk4. Neville Jarvis comments "One important change was made to the drivers cab design on the Mk6 chassis that was an improvement over the Mk4 and this was related to the positioning and operation of the brake and clutch pedals. On the Mk4 both pedals worked longitudinally in slots cut in the floorplate. The pedals on the Mk6 operated conventially through holes in the floorplate. I believe that both Mk4 and Mk6 chassis were available in this improved configuration."

"Having driven Fleet Number 8, the first Seddon to enter service with NST, albeit much later in its service life, I know that it was fitted with the early Mk4 pedal configuration working in slots, and I can attest to its awkward and even dangerous operation. I was later a regular driver of Fleet Number 79 with its improved arrangement and found it a joy to drive. I believe Number 79 to have been a model Mk6/2 and have reached the view that Number 8 was possibly a Mk6/1 i.e. a Mk6 with the early Mk4 pedal arrangement. I cannot recall any other NST Seddon so fitted but there may have been others."

"I have deduced from the Seddon photographs, and by projecting a drawing of a Seddon body over that of a Daimler CVG5, that the 16 ft 4in wheelbase was standard throughout the fleet of 14 buses that entered service between 1951 and 1956." As all had a 16ft 4in wheelbase this would confirm that they are all Mk 6 chassis.
