After graduation he began studying towards a degree in business and advertising at the Auckland University of Technology while playing his club rugby for Grammar TEC with whom he won the Gallaher Shield in 2013.

A career highlight for Pryor and his side was the 2014 ITM Cup, where a 3rd-place finish on the Championship log ensured they would appear in the playoffs.

[12] His first season with the 'Landers turned out to be a dream with the franchise going on to win the Super Rugby title for the first time in their history after a 21–14 victory over the Hurricanes in the final.

[13] He played a further 16 times the following year, however, owing to strong competition among loose forwards such as Shane Christie, Luke Whitelock, Elliot Dixon and Liam Squire, he was only able to start 5 matches as the Highlanders were unable to retain their Super Rugby crown, losing out to the Lions in the semi-finals.

[5] Pryor was named in the Māori All Blacks squad ahead of the 2014 end-of-year rugby union internationals and debuted in a 61–21 win over Japan in Kobe, coming on to the field as a 49th minute replacement for future Highlanders teammate Elliot Dixon.
