Getting an ADHD assessment can be the first step towards understanding many of your past and current difficulties and explaining what you've been experiencing since childhood.​ Here are some tips to help you through the process. 

Our self-assessment tool

ADHD New Zealand's self-screening tool is a good place for adults to start. You can share the results with your GP or a health care professional who specialises in dealing with ADHD. You can find the tool here:

Seeing your GP or going directly to a provider

Your general practitioner (GP) can guide you through the process for getting an assessment and make recommendations specific to your situation (such as using insurance, the type of specialist, referring you to the specialist and what you need to take with you).

A number of private practices allow self-referrals, so if you are comfortable with the process, going directly to a specialist who does ADHD assessments is also an option. 

Who can prescribe and diagnose? 

New rules for prescribing stimulant medicines and diagnosing ADHD (effect of 1 February 2026) and an update to the New Zealand Clinical Principles Framework for ADHD, widen the scope of people able to support you. According to these: 

• A registered medical with competence in working with ADHD should undertake assessment and diagnosis
• Quality care for ADHD is based on the development of competence in working with ADHD, rather than qualification alone. 

Assessing and diagnosing children and young people 

Health care professionals competent in working with ADHD and people in these age groups may include: 

• nurse practitioners working within paediatric services and child and adolescent mental health services
• psychologists
  
• vocationally registered paediatricians and
  
• vocationally registered psychiatrists. 
  

Assessing and diagnosing adults

Health care professionals competent in working with ADHD may include:

• vocationally registered general practitioners

Using insurance 

Some insurers are challenged in identifying the distinction between mental health and non-neurotypical conditions. So they take the stance of excluding the whole lot. Other insurers have recognised the challenges in the mental health support community and have relaxed their requirements.

When choosing your health care professional 

You may be seeing this person regularly so make sure, once you’ve met them, that you’re comfortable sharing personal information with them. Depending on how regularly you are seeing them, travel may also be a consideration.

Questions you may want to ask them to include: 

• How long have you been working with people with ADHD? 
  
• Have you received any training in the diagnosis or treatment of ADHD? 
  
• What is involved in the assessment—written tests/interviews? 
• What sort of treatment plan do you use — behaviour modification, medication, alternative therapies? 
• What are the costs involved? 
• Do you accept my insurance?

Preparing to see your health care professional 

There is often a wait to see a health care professional who specialises in ADHD so, if you can, try to book an appointment ahead of when you might need it (i.e. before school/uni term, beginning a new job etc.)

They'll likely send you some forms and questionnaires to complete and send to them before the meeting and will review these before your first meeting with them.

What an ADHD assessment involves 

A proper ADHD assessment should do two things:

• determine whether a person has ADHD and rule out other potential reasons for the symptoms, and
• identify any other potential challenges such as anxiety, depression, dyslexia, autism, auditory processing disorder or obsessive compulsive disorder.
  

Your first session is likely to take 60 to 90 minutes, and a typical assessment for adult ADHD may take up to three hours.

Common assessments include: 

• ADHD rating questionnaires (called psychometrics)
  
• cognitive assessments (assessing cognitive strengths, weaknesses and IQ)
• mental health broad screener questionnaires (psychometrics to help narrow down the areas the assessment will need to focus on and/orneuropsychological assessment of the attention system or executive functioning.
  

What you might be asked

You may be asked to elaborate on aspects of your questionaire results such as:

• how often do you quit a task before you're done?
• how often do you misplace things?
• how often do you forget appointments or other important matters?
• do you have trouble sitting still?
  
• do you struggle to relax?
• how often are you distracted by things around you? 
• development, health, family, and lifestyle history
• strengths, weaknesses and some of the challenges you’ve been facing.

Your medical history is also an important part of the evaluation. If you haven't had a medical exam recently, one might be recommended to rule out medical causes for your symptoms. They will also assess whether any co-existing conditions are present, because if co-exisiting conditions aren't treated then treatment for ADHD may not be as effective.

Things to take to your assessment 

• Your fully completed questionnaires (send in before appointment so they can be reviewed and scored)
  
• Completed questionnaires from others. In the case of children, your specialist may want to talk to a teacher, coach, or day care provider. For adults they may want to talk to a partner or family member. 
• Memory for a detailed developmental, social and family history (taking your/your child’s Well Child/Plunket book and school reports is helpful), and or
• any supporting evidence (such as medical, psychological, school/employment records, or if you're an adult, a copy of the results from our self-screening tool) to the appointment.
  

What happens next? 

ADHD is catagorised according to a set of criteria that all appropriately trained clinicians use. The diagnostic system used in New Zealand is called the DSM-V, which we share with most of the English speaking world (except Europe).

​Once your specialist is satisfied that their review is conclusive, they’ll share their thoughts with you. This may, or may not, result in you receiving a diagnosis for ADHD.​​

If you get a diagnosis that confirms you have ADHD, this can be an enormous relief as it often helps you to understand there is a reason for many of your current and past difficulties.

They’ll share their thoughts with you around the diagnosis and a treatment plan to suit.
