Sydney-based heavyweight Hunt, who fights Alistair Overeem today in UFC 209 in Las Vegas, has expressed his enthusiasm about fighting again in the country of his birth, but much will depend on his return to the cage against UK-born Dutchman Overeem.
A win will give Hunt's career a big boost following his disappointment at losing to American Brock Lesnar and Lesnar's subsequent drugs test failure last June. Hunt hasn't fought since and complained of being "ostracised" by the UFC despite not doing anything wrong.
Hunt, 42, is back in the fold now, though, and a victory would push his case to headline the Auckland card.
Whittaker, a New Zealand-born middleweight also based in Sydney, could also make a good case. The 26-year-old has lost only four times in 22 fights, and scored an important victory against Derek Brunson in November, a first-round TKO win which earned him a performance-of-the-night bonus.
Hunt told the Herald on Sunday: "Of course it would be good to fight where I grew up and where I was born. And there are a lot of people there who helped me along this journey of fighting - for myself, being one of the best fighters coming from a negative [background] to a positive, I think it's great news.
"It goes to show that regardless of your upbringing, you can always turn things around through hard work."
Hunt's traumatic upbringing in South Auckland is well-documented in his book Born to Fight. His resilience in the face of his father's regular beatings combined with Hunt's durability and punching power in the octagon have made him a favourite in New Zealand and Australia, and a return to Auckland would be extremely popular.
Kiwi middleweight James Te Huna headlined the 2014 card at Vector Arena, a loss to American Nate Marquardt.
Carr said: "We've always felt that our live events are our best marketing tool in terms of acquiring new fans and growing interest in the sport. When we bring the show to town for the full week, you can't recreate that media and PR buzz that we generate with all the fighters in town."
Carr said the UFC were expecting big demand for tickets, which will probably go on sale next month.
A pre-registration website - www.ufc.co.nz/auckland - will be launched today.
