A statement from Northland Rugby confirmed the death of a player regarded as one of the country's great halfbacks.
Going played 86 matches for the All Blacks over a decade-long span in the 1960s and '70s, including 29 tests.
Northland rugby said: "It is with great sadness that we acknowledge the passing of our province’s Sid Going.
"Together, from Te Kao to Mahurangi, from our North Auckland days, and across the country, we will respectfully mourn his passing, but also remember all that he has given to our game of rugby."
