Lock, Stan van den Hoven, moved to New Zealand from the Netherlands and he clearly impressed quickly, as he not only made the BOP provincial squad but in 2017 was named U19 player of the year at Bay of Plenty (in a team that had four New Zealand U20 squad members).

He was also selected to train with the New Zealand U20 squad, and part of the Chiefs Development squad. He was named in the 2021 Squad but did not make his debut.
