He was then knocked out in the first round of his UFC 170 showdown against Stephen Thompson in January meaning Whittaker (12-4) is now under pressure to register a win when he meets Rhodes.
"I've assessed a lot of reasons why I lost and you just go back to the drawing board ... they say you learn a lot more from a loss than a win," the 23-year-old said. "I can make it up now and the fact this is also making history with the first UFC event to come to New Zealand - it's huge."
Whittaker was born at Auckland's Middlemore Hospital but moved across the ditch with his family when he was 1 and was raised in Sydney, where he is still based.
Kiwi James Te Huna (16-7) will headline the June 28 card in a middleweight bout with veteran American Nate Marquardt (32-13-2).
After losing his past two bouts at light heavyweight, next month's match will mark Te Huna's debut at middleweight.
