Jason David O'Halloran (born 28 February 1972 in Lower Hutt, New Zealand) is an All Black cap and rugby union coach.
A perceptive playmaker and astute tactician, O’Halloran was often the unsung hero in a backline glittering with big-name stars, with his 35 tries for Wellington and 17 for the Hurricanes all scored from the midfield testament to his ability.
For until then there seemed every chance that the only other All Black appearance O'Halloran had made, on the way to Europe against the Asian Barbarians, would not entitle him to official recognition as a New Zealand representative.
And subsequently when the All Black touring party reached Europe for internationals against France and Italy O'Halloran had to drop out for the first week or so because of a family bereavement.
In October 2007 he was appointed High Performance Academy Manager by the Manawatu Rugby Union, having spent the previous two seasons coaching at Japanese club, Kubota.
In October 2011 he was appointed as Head Coach of the Manawatu Turbos ITM Cup team, succeeding Dave Rennie who moved to the Chiefs.
O'Halloran stated: "Suntory have a reputation for playing a fast paced, attacking brand of rugby and this fits nicely with my own personal philosophy toward the game.
The club website stated Jason had no set return date and in his absence Tony Brown would step in on a short-term coaching consultant role.
