Glen Warwick Jackson (born 23 October 1975 in Feilding, New Zealand) is a professional full-time referee for New Zealand Rugby. Jackson is also a former New Zealand rugby union player. During his playing career, he was a first five-eighth. Domestically, he represented Bay of Plenty and Waikato in the NPC and the Saracens in the UK's Guinness Premiership. His strong performances saw him named in the Chiefs squad for the 1999 Super Rugby season and had international experience as well with New Zealand M?ori (now known as the M?ori All Blacks) and the Barbarians.
He made his debut for the Chiefs in the opening round of the 1999 Super 12 season. Jackson made his final appearance for the Chiefs in a 2004 Super 12 semi-final defeat to the Brumbies. Jackson was a member of the New Zealand M?ori side that won the 2004 Churchill Cup. He signed for Saracens in 2004.
In 2010 Jackson retired to become a professional referee in his native New Zealand. He was fast-tracked into the professional rugby ranks by Lyndon Bray, then the head of referees for the New Zealand Rugby Union (now known as New Zealand Rugby) and later in the same role with SANZAAR, organiser of Super Rugby and The Rugby Championship (formerly the Tri Nations). Within a year of Jackson's return to New Zealand, he went from refereeing provincial rugby games in the Heartland Championship to officiating in the ITM Cup at the top provincial level to being an assistant referee in Super Rugby competition. By the end of the 2011 Super Rugby season, he had worked his first match as referee in that competition, having presided over the Hurricanes-Western Force match on 27 May. Shortly after the end of that season, he made his international officiating debut as television match official for the Bledisloe Cup Test between New Zealand and Australia on 6 August. On 15 February 2015 he made his Six Nations refereeing debut when he took charge of the Scotland-Wales match at Murrayfield. Jackson was the first New Zealander to play and referee 100 first class fixtures when he took charge of the Argentina v South Africa match on 15 August 2015. He retired as a referee after he was not selected for the 2019 Rugby World Cup.
