[7] Hemopo first made the Otago squad ahead of the 2014 ITM Cup and went on to play all 10 of their games during what proved to be a difficult year, with an inexperienced side finishing 6th on the Championship log, comfortably outside the playoff places.
[2] Although not initially named in the Highlanders squad for the 2015 Super Rugby season, injuries among the franchise's forward pack saw the versatile Hemopo called up to provide short-term cover midway through the year.
[6] During the 2018 three-test series against France, Hemopo was called into the New Zealand national rugby union team, the All Blacks, as injury cover alongside Highlanders teammate Tom Franklin.
After proving himself as a promising player during training, Hemopo was named to make his All Black debut in the third and final test of the series, on 23 June 2018.
Hemopo made a short cameo off the bench during the first half of the test while Highlanders teammate Shannon Frizell, who was also on debut, was in the blood bin.
However, after outstanding performances by Ardie Savea and Patrick Tuipulotu, Hemopo missed out on the All Blacks' 31-man squad for the 2019 Rugby World Cup.
