General Power of Attorney (New Zealand)

The key difference between a general power of attorney and an Enduring Power of Attorney (EPA) in New Zealand is what happens if the donor loses mental capacity. A general power of attorney — made under the common law and the Contract and Commercial Law Act 2017 — is automatically revoked the moment the donor becomes mentally incapable. This means that if the donor suffers a stroke, dementia, a serious accident, or any other event that causes mental incapacity, the attorney's authority immediately ceases and the attorney can no longer act. An Enduring Power of Attorney (EPA), by contrast, is made under the Protection of Personal and Property Rights Act 1988 (PPPR Act) and is specifically designed to 'endure' through mental incapacity — hence the name. An EPA continues in force even after the donor becomes mentally incapable, which is its primary purpose: to authorise the attorney to act precisely when the donor can no longer make decisions for themselves. For estate planning purposes, an EPA is almost always preferable to a general power of attorney. A general power of attorney is suitable only for short-term, specific situations where the donor is healthy and capable but temporarily unable to attend to their affairs in person.

A general power of attorney gives the attorney broad authority to act on the donor's behalf in legal and financial matters. The extent of the attorney's authority depends on how the document is drafted — a broadly worded general power of attorney can authorise the attorney to do virtually anything the donor could lawfully do in respect of the donor's property and financial affairs. This can include: managing the donor's bank accounts; paying bills and expenses; entering into contracts on the donor's behalf; dealing with the donor's real property including buying, selling, mortgaging, and leasing; managing the donor's investments; collecting money owed to the donor; filing returns and dealing with Inland Revenue; dealing with NZTA in respect of vehicles; and generally conducting any financial or legal transaction on the donor's behalf. A general power of attorney does not authorise the attorney to make a will on the donor's behalf, make personal care or healthcare decisions, or take actions that are inherently personal to the donor. It is good practice to specify clearly in the document what the attorney is and is not authorised to do.

Third parties in New Zealand — such as banks, real estate agents, lawyers, NZTA, and other organisations — are not always obliged to accept a power of attorney, particularly if they have concerns about its validity or the scope of the attorney's authority. To maximise the likelihood that a third party will accept a power of attorney, the following steps are recommended. First, have the document professionally drafted by a solicitor and executed correctly — it should be clearly written, properly signed, and witnessed by a JP or solicitor. Second, include a clear statement of the scope of the attorney's authority and the specific transactions the attorney is authorised to complete. Third, include the donor's full name, address, and identifying details, and the attorney's full name and address. Fourth, include the date of the power of attorney and any expiry date. Fifth, have the power of attorney certified or notarised if the third party requires it. Some banks and financial institutions have their own power of attorney forms — check with the institution before relying on a general template. Sixth, if the power of attorney is to be used overseas, it may need to be apostilled by the New Zealand Department of Internal Affairs.

A general power of attorney in New Zealand expires in the following circumstances: (1) if a specific end date is stated in the document — it expires automatically on that date; (2) if the donor revokes the power of attorney in writing and gives notice to the attorney — it expires when the attorney receives notice of the revocation; (3) if the donor becomes mentally incapable — a general power of attorney (unlike an enduring power of attorney) is automatically revoked by the donor's incapacity; (4) if the donor dies — a power of attorney is automatically revoked by the donor's death; (5) if the specific purpose for which the power of attorney was granted has been completed — for example, if a property purchase is completed, a motor vehicle power of attorney for that purchase automatically expires; and (6) if the attorney becomes incapable of acting — for example, if the attorney dies or becomes mentally incapable. For ongoing authority that survives incapacity, an Enduring Power of Attorney under the PPPR Act 1988 must be used instead.

A General Power of Attorney (New Zealand) does not legally require a lawyer in New Zealand, and individuals and businesses may draft and execute the document independently. The Protection of Personal and Property Rights Act 1988 does not mandate legal representation for the creation or signing of this type of document. However, seeking independent legal advice from a qualified New Zealand lawyer is recommended for transactions involving substantial financial value, complex regulatory requirements, or cross-border elements where multiple legal jurisdictions may apply. A lawyer can verify that the document complies with all applicable statutory requirements, identify potential risks specific to the transaction, and confirm that the terms adequately protect the interests of all parties involved. The High Court of New Zealand has jurisdiction over disputes arising from this type of document, and Companies Office may impose additional compliance obligations depending on the nature of the underlying transaction. Professional legal review is particularly advisable where the document will be submitted to government agencies or used as evidence in legal proceedings.
