[7] Gibson-Park debuted for Taranaki in 2012, playing the season's first two Ranfurly Shield matches against King Country and Wanganui.

He was contracted and made the Taranaki National Provincial Championship squad, making his NPC debut starting at scrum-half against Bay of Plenty.

He received high praise from television, print and radio commentators and had been named one of the five promising players of the year by the Rugby Almanack.

Gibson-Park was also a part of the Blues team to face France, getting his chance because of injury with All Blacks halfback Piri Weepu.

[11] Gibson-Park recorded one try while also being pointed out by many commentators as a key figure for the Blues,[citation needed] in what was his final season.

[13] In September 2017, Gibson-Park and Leinster captain Isa Nacewa were denied entry in to South Africa due to visa restrictions.

[15][16] Gibson-Park was selected in Leinster's defeat to La Rochelle in the 2023 European Rugby Champions Cup final.

[17] Although the then 20-year-old Gibson-Park had only played eleven matches for Taranaki, Jamie Joseph, the Māori All Blacks coach, selected him for the 2012 end of year tour to England, playing against domestic club team Leicester Tigers, an invitational RFU Championship XV, and ending against the Canadian national team.
