"How to make a will
Don't have a will yet, or need to update a previous will? You can get one drafted by someone with experience, such as a lawyer or trustee company. A will must also be signed and witnessed. If the proper procedures are not followed, a will may not be valid.
Wills don’t have to be pricey. Some lawyers will even write one for free, so there’s no harm asking around.
Online platforms such as Public Trust and LawHawk also offer low-cost options for wills and enduring powers of attorney. You can also find planning help at Te Hokinga a Wairua.
