Onslow Medical Centre lists its address as 125 Moorefield Road, Johnsonville, Wellington. The official site and Healthpoint both list the phone number as 04 478 9999. Healthpoint lists the Healthlink EDI as onslowmc.
The official contact form is for non-urgent enquiries. The contact page specifically says to phone for appointments and to call 111 for medical emergencies. Do not use a contact form or email if delay could be unsafe.
How to book the right Onslow Medical Centre appointment
The appointment page gives two routes. If you are registered with Manage My Health, you can use the portal to make an appointment with your GP. If you are not registered, or you would like to speak to a staff member about an appointment, call reception on 04 478 9999.
The enrolment pack adds a useful micro-detail: if you require a special appointment or a longer/double appointment, phone reception rather than relying on standard online booking. That is important for users with multiple issues, medical forms, procedures, complex reviews or first-appointment questions.
Check urgency first
Call 111 for emergency symptoms. For same-day non-emergency concerns during opening hours, phone the clinic. For after-hours uncertainty, call Healthline.
Use Manage My Health for suitable routine booking
Use the portal only if you are registered and the appointment is routine enough for online booking.
Phone for special, longer or unclear appointments
Phone reception if the issue involves multiple problems, medical examinations, forms, procedures, complex medication issues, new-patient questions or anything where the appointment length may matter.
Explain the reason clearly
Tell reception whether you need GP, nurse, repeat prescription, allergy appointment, accident care, minor surgery, medical exam, screening, vaccination or urgent same-day advice.
Cancel early if you cannot attend
The enrolment pack states that cancellations must be made within 24 hours of the confirmed appointment and that failure to attend or cancel within 24 hours will incur a fee. Confirm the current cancellation rule directly.
What to say when you call Onslow Medical Centre
Clear wording helps staff route your request. Reception cannot diagnose you, but they can help with the correct booking route, appointment length, clinician type and preparation.

Medical examination

New patient
“I have completed enrolment / want to enrol. What needs to happen before my first doctor appointment?”
