Kelly Club Chelsea runs before and after school care from the school hall at Chelsea Primary School, in Onetaunga Road, Chatswood, for children of the school and the wider Birkenhead and North Shore area. The club has operated from the hall since 2017. Its before and after school care runs from 3 February to 18 December 2026 on the website's listing, and it also runs holiday programmes. The programmes wrap around the school day, and children can do homework and relax after school.
Activities include baking and cooking, sports and games, arts and crafts, science and discovery, reading, and structured free play. The programmes are approved by the Ministry of Social Development, so families who qualify can use an OSCAR subsidy towards the cost, and the club offers flexible payment options. Staff who work with children in OSCAR programmes are police vetted, and the club says the checks are repeated every three years. The website says children from different schools catch up with each other each afternoon at the club.
