For anyone else stumbling across this thread, the INZ 1002 guide gives guidance on how to fill out the INZ 1000 form.
It contains the following statement (emphasis my own):
Answer all the questions in sections A-H that apply to you or to any family members included in your residence application. If a question does not apply to you, write ‘N/A’ or ‘not applicable’ in the box so we know you have not accidentally missed a question. When you have completed sections A-H, you should then complete the section for the category you are applying under, and then Section P: Declaration, Section Q: Immigration adviser’s details, Section R: Declaration by person assisting the applicant (if required) and Section S: Paying your application fee and immigration levy.
Then, on the INZ 1000 form itself, on the page with the section A-H checklist (immediately before section I), it states which section you need to fill in. The following bullet points are quoted directly from the INZ 1000 form:
- If you are applying under Residence from Work Category (including the South Island Contribution resident visa) go to Section I: Residence from Work Category.
- If you are applying under Family: Partnership Category go to Section J: Family: Partnership Category.
- If you are applying under Family: Dependent Child Category go to Section K: Family: Dependent Child Category.
- If you are applying under Refugee Family Support Category go to Section L: Refugee Family Support Category.
- If you are applying under Pacific Access Category go to Section M: Pacific Access Category.
- If you are applying under Samoan Quota Scheme go to Section N: Samoan Quota Scheme.
- If you are applying under Employees of a Relocating Business Category go to Section O: Employees of a Relocating Business Category
