Langham says it is likely another high-profile series will also come to Taupo in the next two years.
"We are well advanced with plans to host a championship which is even more widely recognised," he says.
"Again it's a European series which has not come to this part of the world before, and the organisers are keen to expand their horizons."
Langham says Superleague bosses have given the Taupo circuit a big tick. "The final round of the series makes sense because teams and spectators stay on for a holiday break."
The single-seater Superleague cars are close cousins to F1 cars but use a V12 engine developing 560kW. Drivers can also use a "push-to-pass" button eight times a race, giving them an extra 37kW.
Up to 20 cars and drivers compete for about $5 million in prize money racing under their country's flag, a bit like the old A1GP series.
They race over eight weekends on circuits on four continents.
The qualifying and race format is quite different from any other form of motor racing.
