An explosive ball-carrier and Tongan international Sitaleka was recruited by Wolves in August 2017 on a two years’ contract from the Penrith Panthers whom he helped to reach the NRL play-offs. This has now been extended to the end of 2021. Strong performances with his hometown Manurewa Marlins in Auckland and within the New Zealand Warriors junior system attracted the attention of West Tigers whom he joined in 2013. Sitaleka joined the Panthers for the 2016 campaign, quickly establishing a regular place in the side. He earned his cap for Tonga in 2014 but missed out on World Cup selection in 2017.
