01 — The practice
Integrative medicine applied to general practice.
Primary care outside the public system: diagnosis, treatment, prescriptions, referrals, and prevention. Government funding follows the number of patients a practice has enrolled, rather than the time spent with any one of them. Consultations are shaped accordingly, which serves a common problem well and a complicated one poorly. At Health Function, the length of a consultation and what happens in it follow the patient’s clinical need.
Private General Practice suits people whose health does not call for an extended investigation, but who want a doctor with time. One who explains what a result means for them in particular, and what should be done about it. A doctor who welcomes clinical questions and feedback between appointments. In general practice, an integrative approach assesses sleep, food, environment and anything else that may sit behind an everyday problem.
Medicine applied to the whole person, and to everything they live with.
Light, environment, nutrition, movement, sleep, stress, and what a person believes about their health are assessed alongside conventional care. Where complementary approaches are considered, they are discussed openly and weighed against the evidence and the patient’s circumstances. Conventional treatment is always set out, with what it offers and what it asks. The decision is the patient’s.
It runs as a programme in stages, beginning with a full assessment in the first year and settling into regular review after that. A protocol sets the order of things: which supplements start when, which foods come out and when they go back in. Most protocols are written for a condition. A protocol at Health Function is built around the patient, with the diagnosis informing it without determining it.
Integrative Medicine suits people whose problems have not been settled by the usual investigations or treatments: symptoms that persist alongside normal results, several things happening at once, a diagnosis that accounts for only part of the picture. The work is to find the pattern, and keep testing it as things change.
Health rarely changes in a single appointment.
Registration begins with an assessment of the history and what has already been tried. What follows is a change made, time to see whether it worked, and the next change after that. The cycle cannot be hurried. A change takes weeks to show anything, and a result only means something read against the one before it. A year is the shortest period in which that can happen more than once.
That is also what the year asks in return. Changes to sleep, food, environment, medication and supplements take effort to sustain, and the ones that work are rarely the easiest in the first fortnight. Registration is accepted on that understanding.
What this practice does is work out what is actually going on, and stay with it. A single appointment with someone whose full history and response to interventions are unknown cannot do that, which is why one-off consultations are not offered. That is what a year is for.
At least the first consultation is in person, wherever a patient lives. Patients in Nelson are asked to attend in person for follow-ups when possible, and those living further away can be seen by telephone or video. Everyone is asked to be seen in person at least once a year. Where mobility or illness makes travel impractical, a different arrangement is agreed.
The clinic is in a garden setting, complete with a view and birdsong. As there is no waiting room, patients are asked to arrive at the clinic door no more than 5 minutes before their appointment start. Ring the red bell on arrival.
02 — Between appointments
An appointment is a few hours a year. Between them sit the results that have to be read against the last set, the plan that needs changing before the next review, the prescription that should not wait, and the clinical questions asked by patients.
A written summary follows every consultation: what was discussed, what was decided, and the plan from here. Results are returned with what they mean. Prescriptions and laboratory requests are actioned without an appointment. Referrals are made when they are needed. For Integrative Medicine patients, protocols are revised as results arrive, recorded in the notes and sent out without waiting for the next review.
All of it is done by the same doctor — the one who wrote the last summary and ordered the test being asked about. None of it is billed separately. Questions can be sent through the portal at any time, without an appointment, and are answered within two working days.
Consultations are held on Tuesdays and Wednesdays for follow-up appointments, and on Thursdays for new patients. The days without clinics are when the work between appointments is done, so prescriptions, results and questions are dealt with whether or not there is a clinic that day. The practice closes for two weeks over Christmas. Prescriptions, messages and results are not actioned during that time, so anything needed over the holidays should be requested beforehand. Urgent matters during the closure go to your usual practice or the after-hours service.
03 — The doctor
Thirty years in medicine, twenty-five of them integrative.
Dr de Villiers has worked in general practice and in remote emergency departments, across a wide range of patients and problems. The move toward integrative medicine came from what she saw in ordinary consulting, from life, and from staying open to knowledge that continues to change. What she kept noticing was that how a person eats, sleeps, moves and lives accounts for a great deal of what arrives in the room, and that it differs from one person to the next.
She holds a Fellowship of the Australasian College of Nutritional and Environmental Medicine. That training supports practical decisions about which investigations are worth ordering for a particular person, what a set of results means read together rather than one line at a time, and how a protocol is built for one person rather than for a condition. The fellowship is only the examined part. The reading, experience and case work are continuous.
The practice stays grounded in conventional medicine — examination, investigation, prescribing and referral where they are needed. The integrative work is added to that.
Registration and qualifications
Any doctor's registration can be verified on the Medical Council of New Zealand's public register.
04 — Fees
A subscription for the year, rather than a fee for each visit.
Two streams, and two ways to begin. A new patient registers either in Private General
Practice or in Integrative Medicine · Establishing.
The two later Integrative subscriptions follow by agreement at the end of a subscription
year.
| Subscription | Consultations included | Monthly | Year |
|---|---|---|---|
| Private General Practice | 2 × 30 min | $60 | $720 |
| Integrative · Establishingwhere Integrative begins | 90 min initial appointment, then 3 × 60 minThe 90 min initial appointment can be taken as 60 min plus a 30 min follow-up, usually at four to six weeks. | $250 | $3,000 |
| Integrative · Refiningfrom year two, by agreement | 4 × 60 min | $210 | $2,520 |
| Integrative · Maintaininglater years, by agreement | 1 × 60 min + 1 × 30 min | $133 | $1,596 |
All fees are in New Zealand dollars and include GST.
Registration. A one-off fee is charged when an application is accepted — $75 for Private General Practice, $150 for Integrative Medicine. It covers setting up the medical record, portal access, and reviewing the history before the first consultation.
Further consultations. Beyond those a subscription includes, appointments are charged individually.
Nobody can predict whether a new concern will arise, or whether more consultations will be needed. They are booked as they come up.
Testing and supplements. Functional testing, non-subsidised laboratory testing and imaging, and supplements sit outside the subscription and are purchased through third parties. Health Function receives no commission on any test or supplement recommended.
When you are charged. Once an application is accepted and the consents given, the first month is paid. The medical record is created at that point. After that, subscriptions are billed monthly and debited automatically from a credit or debit card on the same date each month. Bank transfers are not accepted. Payments are handled by Stripe, so card details are held by Stripe and never by Health Function. A receipt is sent every time, and the card on file can be changed at any time from your Health Function account (opens in Stripe). Fees may change at the start of a new subscription year, and do not change during one.
Cancellation. Registration is for a year, and a subscription can be cancelled at any time from your Health Function account (opens in Stripe), without having to ask. The aim here is to stop watching the clock, so there is give and take in how a year is used. Consultations not used within a subscription year do not carry over to the next, and a year works best when appointments are spaced through it rather than saved up.
05 — Questions
Everything here is answered above. This is the short version.
Conventional medicine with a wider assessment and management. Sleep, food, movement, light, environment and stress are examined alongside the usual history and investigations, and often turn out to be part of the problem. Treatment follows from what that assessment finds, whether that is a prescription, a dietary or lifestyle change, or a supplement. The options are set out with what each one offers and asks, and the choice is yours.
No. The practice works only with registered patients. A single appointment with someone whose full history and response to interventions are unknown cannot do what this practice is for. Registration is for a year.
No. The practice is based in Nelson and sees patients throughout New Zealand. At least the first consultation is in person wherever you live, and everyone is asked to be seen in person at least once a year. Follow-ups in between can be by telephone or video. Where mobility or illness makes travel definitely impractical, a different arrangement can be agreed.
Applications can be made at any time. A place is offered when one opens and the practice is right for what that person needs.
Dr de Villiers reads every application herself, and you will hear back within two weeks. If a place is available and the practice suits what you need, she will be in touch. Accepting a place means agreeing to the consents and terms, paying the registration fee and the first month, and completing a medical history form. The medical record is created at that point.
Each subscription year ends with a review. It covers what has changed, when you were last seen in person, and which subscription fits the year ahead. Private General Practice usually continues as it is. Integrative Medicine patients generally move from Establishing to Refining, and later to Maintaining, as the work of the early years is done. Payment continues monthly into the next year once the review is done.
Yes, and it is encouraged but not mandatory. Health Function registers patients; it does not enrol them. Enrolment is the arrangement between you, a general practice and its Primary Health Organisation, and Health Function is not part of one. Dr de Villiers is the primary care provider for some patients and works alongside an enrolled GP for others. Keeping your enrolment means the services of a PHO practice, such as vaccinations, stay available to you.
No. Health Function is not part of a Primary Health Organisation, and vaccinations, care plans and other Primary Care funded services are not available here. They remain available through a PHO-enrolled general practice. Vaccinations are also available from after-hours clinics where you would be seen as a casual patient, or from a pharmacy that offers them.
Health Function is not an emergency or after-hours service. In an emergency always call 111. For urgent after-hours advice call Healthline on 0800 611 116, or use your usual after-hours clinic; after-hours services can be used whether or not you are enrolled elsewhere.
A single lesion that concerns you can be checked at a consultation. Full skin checks, biopsies and excisions are done by GP skin clinics or dermatologists, and a referral is made where needed.
Clinical records are held in the practice's clinical record system in accordance with the Health Information Privacy Code 2020. The application form on this website is processed by Formspark, whose servers are outside New Zealand; what you enter is used only to assess and manage your application. Once registered, clinical communication takes place through the patient portal.
