Recently the laws changed in New Zealand, which means the old forms package was no longer valid.
In particular, the old 10 day notice has been replaced by a 14 day notice. The forms package has therefore been updated. For anyone who has downloaded the previous 10 day notices, it is recommended you delete those templates, and download the new templates from here
The New Zealand templates are free.
You can also see the same templates and additional forms on the New Zealand Tenancy Services web site.
