Local community involvement is an important part of Targa NZ and as much as $100,000 will be channelled back into local schools and sports groups during the time the event travels from Auckland early tomorrow morning to when it finishes in Havelock North on Saturday - which is also Alex's 56th birthday. At least $50,000 is expected to be raised for the event's official charity Cure Kids, bringing the total amount the event has raised for the charity since 2002 to $500,000.
Cure Kids funds research into childhood illnesses and this is something the Allans consider very important, particularly after seeing their son go through a horrific ordeal nine years ago.
In 2002 Rhodes was badly hurt in an accident during the Rally of Whangarei and suffered extensive head injuries.
"It took him two years to get back to where he is now ... when you see our son go through a head injury and then look at where he is today ... it's hard to explain but it changes your outlook on life," Allan said.
These days Rhodes lives in Auckland, where he is a mechanical technician for Independent Prestige Giltrap Group.
While he was anxious when he first began driving again after his accident, Allan said his son is relaxed again - although perhaps more careful. "But that also comes with the job - you have to be smart when you are driving half a million dollars worth of car for a living.
"He has always been sensible but he is probably more wiser now ... hopefully we can share the driving - but only if I'm allowed - Rhodes is in charge," Allan quipped.
Targa NZ will be the pair's first crack at racing in a rally together and although they have a close relationship, Rhodes has already jokingly told his dad he will turn off the intercom if he interferes too much from the passenger seat.
The father and son duo depart Auckland's Wynyard Quarter midfield in their Suzuki Ignis, which was first raced by Kiwi rally driver Emma Gilmour in the 2004 Targa NZ event.
The Allans bought the car three years ago and refined it. They are looking forward to racing it over the next few days and experiencing an adventure to remember.
