Having previously represented the Melbourne Rebels in the Super Rugby Competition last year, the first-five eight will be the next man up should the team spell star no.10 Beauden Barrett.
Garden-Bachop comes from a family with a huge sporting pedigree, as his father Stephen Bachop was a former All Black and his mother Sue represented the Silver Ferns.
His uncle Graeme Bachop, a halfback, pulled on the black jersey 31 times, including two World Cups, and also represented Samoa at the highest level.
He is also cousins with former Crusaders and All Blacks second-five Aaron Mauger, who is now coaching the Highlanders.
Garden-Bachop himself has represented New Zealand at the schoolboys and U20 level, after making his debut for the Wellington Lions in 2013.
The 23 year old has a two-year contract with the Hurricanes.
