The year of 1970 would bring new winds to all motorsport in the Southeast Asia and Oceania region. New Zealand and Australia, which were the region’s main exponents in this sporting discipline, had promoted a major and risky change, by substantially modernizing their sporting regulations, which had been in force since the mid-1960s. Both countries were so preponderant in this macro-regional scenario, that the changes promoted by them would impact not only the Tasman Series, the New Zealand Gold Star and the Australian Golden Star, but also, soon spread to all nearby countries, promoting a revolution on the tracks that had not been seen in the region for a long time.
The main one, without a doubt, was the official replacement of the “Formula Tasman”, which since 1964 had set the tone for the Formula racing in the region, by the “Tasman Cup” regulations. The old regulations, which stipulated that only engines ranging from 1.6-liter to 2.5-liter could compete in ranked single-seater events in Oceania, began to lag behind, largely due to developments in the area around the combustion engineering that had taken place since the mid-1960s.
