How to make a referral to the AYA Cancer Service

Referrals should be made to the AYA Cancer Service when there is a high suspicion of cancer. Early involvement of this specialist service helps young people and their whānau to navigate services and ensures that important AYA-specific issues are addressed early, including fertility preservation and clinical trial enrolment.

We welcome referrals from young people and their whānau, general practitioners (GP), NGO providers and cancer services staff such as nurses, social workers, specialists and psychologists. Make your referral by contacting either the keyworker or clinical lead.
