Always good seeing New Zealanders sign overseas and he might not be the only one from Birkenhead, as Jackson Woods has apparently left to possibly try things overseas somewhere. Even better when it's a Westlaker - a few have had moves in the last couple months, Sam Brotherton, Deklan Wynne and Moses Dyer also - maybe Woods or McCowatt can hopefully be the next.
Piper is a defensive midfielder in a 'destroyer' player profile, physical and strong in challenges both aerially and on the ground, more so than a passer like Joe Bell for example.
This website gives a decent description of what a destroyer kind of does, though that's just my opinion of his player profile.
For those who find such trivia interesting - I'm pretty sure Piper was one in of those 13th/14th-grade 'superteams' you occasionally find. At North Shore United (though originally Forrest Hill) for the '02 born kids, they had a team (I'm fairly certain) with Piper, Ben Old, Joe Lee (Auckland City), Max Drake and Harry Bark (2019 U17 WC squad members), Levi Wilson (also Birkenhead) and coached by Paul Temple (who was certainly instrumental in bringing them all down to the Phoenix/Lower Hutt). Piper himself was a non-travelling reserve for that 2019 U17 WC, so that team could've even had five members to represent NZ at U16/U17 level.
