Sharon Erwood has been an active member of the Canterbury Basketball Association for many years, but her involvement in basketball started in 1980 with the Nelson Giants. She started by manually managing the stats, but embraced the move to the computerised format in the 1990’s when it came along. She was a member of the Nelson Basketball Association Committee for many years, and it was during this time that she started her refereeing career. In 2003 she moved to Christchurch and continued to be actively involved in basketball with the Canterbury Basketball Association. She has managed several school teams, while also providing stats for those teams. She was the treasurer for the former Canterbury Basketball Officials Association, during which time she took up refereeing again. She was part of the stats roster for the FIBA U19 World Champs in 2009 and was appointed to the stats team for the final.
