After finishing secondary school, Broughton headed to the Bay of Plenty region in the north-east of New Zealand's North Island, where he initially played his club rugby for Arataki Sports Club. On 4 September 2019, he was named in the Bay of Plenty Toa (Under 19) team for that year's Jock Hobbs Memorial National U19 tournament.[8] The following year, then playing his club rugby for the Rangiuru Sports Club, Broughton was again selected for the Bay of Plenty Toa team for a series of games against other provincial under 19 sides.[9]
In April 2021, Broughton played for the Chiefs Under 20 squad that won the first ever Super Rugby Aotearoa Under 20 tournament that was held in Taupō, after remaining unbeaten in all three rounds.[10][11] A year later, he again played for the winning and unbeaten team of the tournament, however, this time that was the New Zealand Barbarians Under 21 team.[12] He was one of the stand-outs of his team during the tournament and created a highlight by chipping the ball over his head at 5m from the Highlanders Under 20's try line. Barbarians team mate Will Gualter caught the ball and dotted down for a try.[13]
