The Network has its origins in the Paediatric Oncology Steering Group (POSG), which was established in 1999. The Paediatric Oncology Steering Group operated for over 10 years and was responsible for some key initiatives that are embedded in the child cancer services that are in place today – the Late Effects Assessment Programme (LEAP), the New Zealand Child Cancer Registry (NZCCR), and Clinical Research Assistants to support Clinical Trials and National Clinical Guidelines.
