The Car is Hugh Kettelwell's and that is him walking between the cars - he was my Solicitor when I bought the first house in 1973.
Identified by Alan Boyle, another Mini Racer, was his Solicitor too !!.
Hugh later on had a rather bad racing accident at Pukekohe at another meeting
Interestingly I posted the photo on Facebook " Old NZ Motor Racing " page and Bruce Blacklock as well as Alan Boyle replied about Hugh and the accident.
Alan Boyles Mini - as an aside
My Mini, never raced just thrashed,although did drive around Pukekohe to get to the Flag Marshall point - never realised until then how tight the hairpin is
