Adult ADHD diagnosis in New Zealand requires a GP referral and patience - public wait times can stretch to 18 months. But private and telehealth options have expanded, and PHARMAC funds several medications once you have a diagnosis. This guide takes you through every step.
Getting an ADHD diagnosis as an adult in New Zealand typically requires a GP referral to a psychiatrist, with public wait times that can stretch to 12 months or more in many regions. Private psychiatric assessment is faster but expensive. The telehealth sector has grown, and ADHD New Zealand maintains a directory of ADHD-aware clinicians across the country.
Before your GP appointment, take the ASRS-v1.1 screener. This is the same tool used by New Zealand GPs and psychiatrists as a first-line screening instrument. A positive Part A result gives you something concrete to present. Write down specific examples - how symptoms affect your work, relationships, finances, and daily life - and gather any old school reports with relevant teacher comments.
Based on the WHO-validated ASRS-v1.1. Takes 2 minutes. The same tool used by doctors and psychiatrists as a first step.
Your GP is the starting point for an adult ADHD assessment in New Zealand. They can screen you, discuss your history, and refer you to a psychiatrist for formal diagnosis. Some GPs with ADHD expertise may feel comfortable making a clinical diagnosis themselves, though formal diagnosis in adults is typically made by a psychiatrist.
Take your ASRS screener results and 3–5 specific written examples of how symptoms impair your functioning. School reports are valuable if you have them. Be clear you are seeking a referral for an adult ADHD assessment.
Your GP will take a history and may use rating scales. They can refer you to a psychiatrist through the public system (District Health Board / Te Whatu Ora) or to a private psychiatrist.
Public referrals go to your regional mental health service. Wait times vary but can be 6–18 months in many areas. Private psychiatric assessment is available within weeks but costs $800–$2,000 NZD. Some telehealth options offer faster access.
ADHD New Zealand (adhd.org.nz) maintains a directory of ADHD-aware clinicians across New Zealand, including psychiatrists, psychologists, and GPs with specialist interest in ADHD. This is the most useful starting point for finding a clinician who understands adult ADHD presentation.
| Pathway | Typical cost (NZD) |
|---|---|
| GP consultation | $0–$80 (subsidised) |
| Public psychiatric assessment | Free (via DHB referral) |

If your ADHD is linked to a physical injury covered by ACC, some assessment costs may be covered. This is not a common pathway but is worth discussing with your GP if relevant.
PHARMAC funds several ADHD medications for eligible adults in New Zealand. Methylphenidate (Ritalin, Rubifen) is funded under Special Authority for adults diagnosed by a specialist. Dexamphetamine is available for those who do not tolerate methylphenidate. Lisdexamfetamine (Vyvanse) is not currently PHARMAC-funded for adults and is available only at full cost (~$150–$200/month).
Prescribing for ADHD must be initiated by a specialist (psychiatrist) but can then be managed by your GP under a shared care arrangement.
Takes 2 minutes. Bring your results to your GP appointment as a concrete starting point for a referral.
