Tasman Cup (F5000) races 1970-1975
The Tasman Cup replaced its fading 2.5-litre formula with the new F5000 for the 1970 season. This lasted for six seasons until the Kiwis chose to go their own way in 1976 with the 'Peter Stuyvesant' series and then moving to Formula Pacific (i.e. Formula Atlantic) the next year. The Australian series continued as the Rothmans International.
Sources include Autosport, Motoring News, the F1 Register books and Graham Vercoe's books "Historic Racing Cars of New Zealand" and "The Golden Era of New Zealand Motor Racing". The start point for the results was Bruce Sergent's website but these have subsequently been augmented with a number of other sources.
The start point for the 1970 Tasman results was Bruce Sergent's site which contains full reports on all these races. The 1970 results were then augmented by practice times and other information on R1 Levin and R2 Pukekohe (both in Autosport 15 Jan 1970); R3 Wigram (Autosport 29 Jan 1970); R4 Teretonga (Auto News Vol 3 No 14 9 Feb 1970 and Autosport 29 Jan 1970); R5 Surfers Paradise (Auto News Vol 3 No 15 23 Feb 1970 and Autosport 19 Feb 1970); R6 Warwick Farm (Auto News Vol 3 No 16 9 Mar 1970 and Autosport 26 Feb 1970); and R7 Sandown Park (Auto News Vol 3 No 16 9 Mar 1970 and Autosport 26 Feb 1970). Additional qualifying times have been provided by Milan Fistonic.
Tasman 1971-1975 information has also come from Bruce's site. Race speeds and other details for 1973 and 1974 have been taken from Autocourse. Qualifying times for 1975 have been supplied by Milan Fistonic from Australian Competition Yearbook. Entry lists have been provided by Milan and Bryan Miller.
The 1972 Tasman results are in the process of being augmented by practice times and other information from Autosport, Autoweek, the 1972 Racing Car News Yearbook and Australian Grand Prix. Entry numbers are taken from Autoweek's grids except Teretonga and Surfers Paradise where Autoweek did not publish them. Reports used are those for R1 NZ GP at Pukekohe (Autosport 13 Jan 1972 pp6-8 and Autoweek 5 Feb 1972 pp1,16-17), R2 Levin (Autosport 27 Jan 1972 pp26-27 and Autoweek), R3 Wigram (Autosport 27 Jan 1972 pp14-15 and Autoweek), R4 Teretonga (Autosport 10 Feb 1972 pp22-23 and Autoweek), R5 Surfers Paradise (Autosport 10 Feb 1972 pp12-13 and Autoweek), R6 Warwick Farm (Autosport 24 Feb 1972 pp23-24, 27 and Autoweek), R7 Sandown Park Australian Grand Prix (Autosport 2 Mar 1972 pp32-33, Autoweek, Australian Grand Prix pp362-368) and R8 Adelaide. There is a mistake in Autoweek's NZ GP grid with Ken Smith being mentioned twice so Autosport's grid is used. In other places where the sources didn't agree, Autoweek appeared to be the least reliable.
