ADHD New Zealand is echoing calls for caution when it comes to GPs treating the condition.

GPs will be able to start medical treatment next year for those affected.

The College of Psychiatrists says GPs should only be included if they have accredited training and clear referral and escalation pathways.

ADHD New Zealand Board Member Sarah Hogan says this is a good call.

She says the expansion should be done carefully and with the right knowledge base.
