The Tongan international joined the club from Rochdale Hornets and will add plenty of power to Scorpions’ ranks.
Scorpions’ director of rugby Mark Rowley said: “He’s an old fashioned strong forward that the Welsh rugby crowd are used to seeing. He’s had a lot of experience at this level and we know that he’ll do well for us this season.”
Whitehaven face their third fixture in a week as a gruelling schedule takes its toll.
‘Haven were beaten 60-6 by Halifax on Wednesday night, just three days after David Seeds’ men recorded a 30-22 win over Rochdale.
Now they face the long trip to South Wales to round off a difficult week.
Coach Seeds is likely to make a number of changes to the team that faced Halifax in midweek as he bids to keep his players fresh.
