New Zealand also welcomes back 'Hoonigan' Ken Block who was last in New Zealand back in 2007 and also competed in the World Rally Championship.
He is probably best known for his exploits in the Global Rallycross series his outrageous Gymkhana series of online videos.
The Kiwi lineup is pretty solid as well, despite the absent Mason, with Emma Gilmour (co-driver Anthony McLoughlin) among the leading contenders.
She'll have her work cut with the likes of Alex Kelsey (with Mal Peden), Ben Hunt (with Tony Rawstorn), Andrew Hawkeswood (with Jeff Cress) and David Holder (with Rob Scott) to name but a few.
Leading woman driver Gilmour only competed in two NZRC rounds last year in an all-new Suzuki Swift-based car due to Global Rally Cross commitments in the US.
In 2014 her Suzuki showed promise on occasion before inevitably succumbing to mechanical gremlins.
It wasn't until the end of the season that her crew discovered the head gasket was causing all the problems. The Dunedin-based driver has finished second in the New Zealand championship three times and is determined that this should be her year.
"We've had a look at the roads and they are amazing. There's not a lot of gravel on them and they should be fun," said Gilmour after a recce.
"Anthony [co-driver] has put some good notes together and the car is running fine. We've done a lot of testing and we've done the best we can and are looking forward to rallying at speed.
"We need a little bit of luck to go our way, but we've prepared really well for this event and hope this will be our year to grab the top spot and win my first national title.
"It's a great field for the New Zealand championship and it's going to be an interesting championship with a number of new cars competing.
"It'll be a tough rally to win this weekend and there's going to be some fierce challenges and we're looking forward to a good weekend."
The re-mapped rally covers 282km of gravel roads over 16 special stages. The event started last night with two tests at the William Fraser Memorial Park at Pohe Island. There are eight stages today over four sections of roads repeated in the afternoon.
Wrapping up each run is the 14.82km Helena stage - a new addition starting inland of Helena Bay on the $50 million retreat of Alexander Abramov. There are six more stages tomorrow, finishing at the Whangarei Quayside town basin.
