Israel Dagg (born 6 June 1988) is a New Zealand Rugby union player who plays for the Crusaders in Super Rugby and New Zealand internationally. He has also played for the New Zealand Sevens team, and represents Hawkes Bay in the ITM Cup.
Israel Dagg was born in Marton, New Zealand and attended Lindisfarne College in Hastings, Hawke's Bay.[citation needed] He was also in the first cricket team for his college but played rugby instead.
While in high school, Dagg represented Hawke's Bay at Under 16 and Under 19 level. Dagg attended the Advanced Course at the International Rugby Academy (IRANZ) in April 2006. His course facilitator was current Chiefs coach, Dave Rennie, and former Otago, Otago Highlanders and New Zealand player Jeff Wilson. That year, he became the first secondary school player to be selected for Hawke's Bay since Danny Lee. The 2006 New Zealand Rugby Almanack named him one of its five promising players for 2006.
