Gelling proved himself to be somewhat of a cult hero at Wigan with his eccentric behaviour which included charging down a penalty goal attempt from Brisbane BroncosCorey Parker in golden point extra time of the World Club Series clash between the Broncos and Wigan on 21 February 2015 and riding to and from Wigan's Good Friday victory over local rivals St. Helens on 3 April 2015 on a BMX that he bought from Cash Converters for £100. On 16 June 2015 Gelling signed a new four-year contract with the Wigan club.
2016
In 2016 he refused to apologise for saying that some of the refereeing decisions "pissed me off" in a post match interview on Sky Sports, instead declaring "I speak my mind. I like to think of myself as a man of the people". A nickname which has since stuck. He played in the 2016 Super League Grand Final victory over the Warrington Wolves at Old Trafford.[15]
2017
Gelling was part of the Wigan Warriors team that beat the Cronulla-Sutherland Sharks in the World Club Challenge. He scored his first tries of the season against the Leigh Centurions with a brace on 3 March. He scored against Warrington and the Huddersfield Giants in the next two fixtures. He didn't score again until the match against Huddersfield on 11 August before finishing the season with a try against rivals St. Helens and a brace against Hull FC.
He reported back to Wigan for preseason in preparation for the 2018 Super League season but not long after he asked for a release from his contract after his girlfriend was involved in a car crash.[17] He returned home to New Zealand to be closer to his family and signed a one-year contract with the New Zealand Warriors.[18]
2020
Gelling returned to play Super League, signing a two-year deal with Warrington after his contract in New Zealand expired.
On 30 November 2020, it was announced that Gelling would be leaving Warrington at the end of the 2020 season, by mutual consent.[19]
2021
On 13 April 2021, it was confirmed that Gelling had signed for Leigh, for the 2021 season.[20]
On 17 May 2021, he scored a try during his sides 16-30 loss at home to Wigan. He would then go on to play two more games, in which his final game would be against Hull KR on 30 May.
On 18 May 2021, he was found not guilty of inflicting grievous bodily harm on his former partner, after a jury took just over four hours to deliberate, before acquitting him of the charge following a three-day trial at Liverpool Crown Court.[21]
On 7 June 2021, it was confirmed that Gelling had left the club, and returned home to New Zealand for personal reasons.[22]
International career
Gelling was part of the Cook Islands team that made the 2009 Pacific Cup Final. Gelling played for 'the Kukis' in their 28–24 test-match victory over Lebanon, scoring one try in the match. Gelling represented the Cooks in the 2013 Rugby League World Cup playing 2 out of the 3 matches the Cooks played at the Tournament.
At age 31, and with still plenty to give he played for the Cook Islands in the mid year pacific test against Samoa in which the Cook Islands lost 42-12 with Gelling trying hard to lift his team with spirited runs in the defeat. This resulted in coach Tony Iro selecting him to be part of the Cook Islands team for the Delayed 2021 Rugby League World Cup. Gelling represented the Cook Islands in two of their three group stage matches as they finished with one win at the tournament. Following their second group stage match against Papua New Guinea, Gelling announced his retirement from rugby league for a second time. This followed on from Gelling conducting a bizarre half-time interview with BBC side line reporter Jenna Brooks where instead of talking about the game Gelling spoke about tourism on the Cook Islands, he went on to say "It's raining, we're not really used to it. We're used to the sunshine a palm trees. If you're ever looking for a holiday, wedding, honeymoon, stag do, check out the Cook Islands, it's like a postcard. There's a law out there you can't have any buildings taller than the tallest coconut tree".[23][24]
