Murphy was a rugby league star while attending Upper Hutt College, with his school side going unbeaten for three years with Murphy at the helm. He went to Australia in 2011, with interest from the Penrith Panthers before switching to New Zealand, and to rugby union, in 2012.
He made a mark in Sevens, playing a key role in the Wellington team that won the national title in 2014, ultimately earning a place in the NZ Sevens squad. He made his first and only cap for Wellington in the 15-aside game that same year. In 2016, he made the move north to North Harbour in search of regular game time, and it paid off.
His performances for Blues A and North Harbour saw him earn his first Blues cap in Round 1 of the 2017 season, against the Rebels.
