Yip a Junior Kiwi in 2013 & 2014. From Wellington if I'm not mistaken. Has all the tools to be an outstanding edge back rower in my opinion.
Ricky Stuart however, has been playing him as a prop since he joined the Raiders. With Junior Paulo going to Canberra next season, hopefully It will allow Tapine him to play his best position. Think he'll announce himself to the wider NRL audience next season. The $1.5m over 3 seasons he signed to join Canberra will look like a bargain for the Raiders.
In regards to Rapana agreed he should've been selected for the Kiwis. Kind of surprised there weren't any whispers about him being a possible bolter for Queensland in SOO as he's eligible for them. If Meniga was still coaching Queensland you know he would've been all over that like a wet rash.
Full list of Kiwi eligible players that I've been able to identify playing NRL and lower grades in this thread.
