Most people use a professional service to create their will, and act as their executor. For example, Public Trust can help you to create a new will and also charge a set fee for executing it. See their website for more information
If you’re thinking of writing your own will, you could use a will kit to ensure you have every important detail recorded. Websites like New Zealand Will Kit and Do-it-yourself-Wills offer them for a very low price. You can also find them in your local book store. Just ensure it has been signed and witnessed properly to make sure it’s valid.
Otherwise, Public Trust’s website outlines a number of options they can offer. You can also talk to your family lawyer if you have one.
For more details about getting your will sorted, visit the Citizens Advice Bureau’s website or the NZ Law Society’s comprehensive guide
