Van Gisbergen will become just the third Kiwi driver to win an Australian Touring car title this weekend if he survives an unlikely all or nothing bid from Red Bull Racing Australia teammate Jamie Whincup on the streets of Sydney.
Heading into the season-ending Sydney 500, which will begin on the streets of Sydney Olympic Park with practice on Friday, the new kid on the Red Bull block leads by 191 points and is guaranteed to lock up the title on Saturday if he finishes fifth or better.
And this is just the beginning for the driver they call the "Wild Thing" with four-time Bathurst champion Murphy declaring he is already a great.
Murphy said the soon to be champion was already a household name in New Zealand and arguably the country's best sporting export after the All Blacks.
"He has done everything to put himself on the radar," Murphy said.
"Him, Scott and Fabian are already well known in New Zealand. They follow the sport religiously and he is a genuine sporting identity back home and winning the championship will just cement that.
"We have had Kiwis competing in this sport forever and a day. And we haven't won a title since 1991. This is going to mean a lot to our nation. This will be huge for Kiwi sports freaks all over."
Yep, the "Gis" is set to be a big deal in New Zealand. He may become the most famous non-rugby player in New Zealand who hasn't scaled Mt Everest.
"I personally believe the New Zealand government needs to give motorsport more recognition for the amount of Kiwis that are performing around the world," Murphy said.
"We have a Le Mans winner, LMP1 stars, an Indy Star and soon a Supercars champion. I think it proves motorsport should get a bit more money back home."
Fellow Kiwis Andre Heimgartner and Chris Pither will also race this weekend at the last Sydney 500.
