Ndebele made the announcement at a joint media conference held with eThekwini Mayor Obed Mlaba and chairperson of A1 Team South Africa, Tokyo Sexwale.
Ndebele said although 25 countries took part in the World Cup of motor sport, only 12 were given a chance to host a round of the series.
"It is of great significance that South Africa is one of them.
"It is roads that build the economy and not the economy that builds roads. This is in context of what the spin off will be with the event being held in the province," Ndebele said.
The cost of staging the event including broadcasting to at least 14 countries around the world, the creation of a street track in eThekweni and all other infrastructure and management costs will be about R91.6 million.
Mlaba said the municipality's estimates were that at least 100 000 spectators would attend the event, with half of these being from outside the province and the country.
