Raphael plans a conjoint Bachelor of Laws/Bachelor of Arts degree with his BA majoring in politics and international studies.
In February Whiti will start a Bachelor of Health Sciences with a view to studying medicine and eventually becoming a neurosurgeon.
"I want to specialise in neurology. I've always been fascinated by the nervous system, it pretty much keeps the whole body running," he said.
Whiti, whose iwi is Ngāpuhi and his hapū Te Kapotai, is currently studying biology, chemistry, physics, English, calculus and religious studies. Next month he will sit scholarship exams in the three sciences.
Whiti said the first response he received after applying for the scholarship told him he hadn't been successful.
"I was pretty gutted for about the first five minutes. It felt pretty awkward. But five minutes later I got a second email saying the first one had been a mistake. I was stoked to be honest, I went and gave my mum a big hug.
"It means I don't have to worry about accommodation, so that's a huge financial strain gone. I can focus on doing well in my first year so I can hopefully win some more scholarships."
Mum Vicky Lawson said it was "pretty much unheard of" for a young person in an isolated rural community like Waikare to win a top study award.
"We need to let kids in these kind of communities know that anything is possible," she said.
Whiti's advice to other young Northlanders pursuing academic success is simple: "Study smart and manage your time."
When Whiti isn't studying you can find him at the National Shrine of St Peter Chanel in Russell, where he plays the organ every Sunday.
