Where a patient is under 16, a parent or guardian enters into these Terms on their behalf and is responsible for payment.

Emergency and after-hours care

Health Function provides ongoing planned care for registered patients, and is not an emergency or after-hours service. Dr de Villiers is the primary care provider for some patients and works alongside an enrolled GP for others. Staying enrolled with a general practice is encouraged but not required. In an emergency call 111; for urgent after-hours advice call Healthline on 0800 611 116.

Complementary and alternative medicine

Your consultations may include standard medical treatment alongside complementary and alternative medicine, including nutritional, nutraceutical and herbal therapies, and the investigation and treatment of environmental factors. This may differ from current medical guidelines and may not be scientifically validated. For further information refer to the Medical Council of New Zealand’s statement on complementary and alternative medicine.

Governing law

These Terms are governed by the laws of New Zealand.

These Terms, together with the Rights, Privacy and Consent to Treatment policy, form the agreement between you and Health Function Ltd about your subscription, and replace any earlier terms of trade. If any part of these Terms is held to be invalid or unenforceable, the rest remains in effect. A failure to enforce a provision is not a waiver of it.

Changes

These Terms may be updated from time to time. Where a change affects a current subscription, registered patients are notified by email before it takes effect, and fees do not change during a subscription year. The date at the top of this page shows when the Terms were last updated.
