No Residence Category Reaches Backwards - a New Zealand Grandparent Is Worth Nothing, and Citizenship by Descent Stops at One Generation
Answer
The general rule applies to you
No exception is recorded for citizens of Australia on this topic. That is the answer, not a gap - everything below is the rule you get, unchanged.
195 exceptions recorded across 74 countries · none match Australia to New Zealand · Residency through ancestry
New Zealand has no ancestry route. The Residence section of the Immigration New Zealand Operational Manual divides into eight parts, and the family half of it - the F chapter - is built on living relationships rather than on descent: F2 Partnership, F3 Parent Retirement, F4 Parent, F5 Dependent Child, F6 Sibling and Adult Child, closed to new applicants since 16 May 2012, and F7 inter-country adoption. Every one of them is a route for a relative of someone already in New Zealand, and the direction of travel is downwards or sideways - a partner, a parent, a child - never upwards into a previous generation. The same closure runs through the Citizenship Act 1977. Section 7(1) makes a person born outside New Zealand a citizen by descent only if, at the time of their birth, a parent was a New Zealand citizen otherwise than by descent. A citizen by descent cannot pass citizenship to a child born abroad, and the single exception is where the child would otherwise be stateless. So a grandchild born overseas to a parent also born overseas is outside both halves: no citizenship, and no residence category that names a grandparent. The nearest thing to an ancestral route in New Zealand law is not about New Zealand ancestry at all - the Special Categories chapter holds the Samoan Quota Scheme and the Pacific Access Category, which are nationality ballots rather than descent routes, and the Pitcairn Islanders instruction at S1.1.
At a glance
- Residence category based on ancestry
- None in the Family Categories chapter of the INZ Operational Manual or among the five business residence categories at BA2.1
The Family Categories chapter contains F2 Partnership, F3 Parent Retirement, F4 Parent, F5 Dependent Child, F6 Sibling and Adult Child (closed to applications after 16 May 2012) and F7 inter-country adoption.
- Generations citizenship by descent crosses
- One
Section 7(1)(a) of the Citizenship Act 1977 requires the parent to have been a citizen otherwise than by descent.
- Exception to the one-generation rule
- Only where the child would otherwise be stateless
Section 7(1)(b) of the Citizenship Act 1977.
- Birth in New Zealand
- Confers citizenship by birth only for a birth before 1 January 2006, or with a parent who was a citizen or entitled to be here indefinitely
Section 6(1) of the Citizenship Act 1977. A person born in New Zealand between 1 January 1949 and 31 December 2005 is a citizen whatever their parents' status.
Requirements
- No category exists; descent reaches only to a child born abroad to a parent who was a citizen otherwise than by descent
In detail
Why there is nothing to find
New Zealand's family instructions are addressed to people who have a relative here now. The applicant has to point at a New Zealand citizen or resident who is their partner, their child, or their parent. An ancestry route points the other way - at somebody who was here, often generations ago, and may be dead. No instruction in the manual is built that way, and the Citizenship Act closes the matching door: a citizen by descent cannot pass citizenship on to a child born abroad, so a family that leaves New Zealand loses the thread in the second generation born overseas.
What applies to you
Nothing changes for a citizen of Australia
We have no rule recorded that treats your citizenship differently here, so the general rule above is the one that applies to you. That is an answer, not a gap.

The Operational Manual is where New Zealand's immigration instructions are actually published, and publishing them here is a statutory duty rather than a courtesy: section 25(1) of the Immigration Act 2009 says 'The chief executive must publish immigration instructions', and the Manual's own first page says 'By publishing the Operational Manual, INZ meets its requirements under section 25 of the Immigration Act 2009 to publish Government instructions on granting visas.' Instructions are certified by the Minister under section 22; section 22(8) says they 'are statements of Government policy', and section 72(1) makes a residence decision one that 'must be made in terms of the residence instructions applicable at the time the application was made'. Each instruction topic carries its own 'Effective DD/MM/YYYY' date and, where it has been replaced, a list of the previous instructions under 'PREVIOUS IMMIGRATION INSTRUCTIONS'.

Practical notes
The absence is bounded by three readings: the Residence section index of the INZ Operational Manual, which names its eight parts; instruction BA2.1, which lists the five business residence categories; and the manual's table of contents of 1,556 topics, in which the Family Categories chapter is listed in full. The F chapter's individual instructions other than F3.5 were not read.
The Special Categories chapter S1 to S4 was read in its contents only. The Samoan Quota Scheme and the Pacific Access Category are nationality ballots, which is a different thing from a descent route, but that judgement is made from their titles and the names of their sub-instructions rather than from their text.
The Citizenship (Western Samoa) Act 1982, which section 7(1)(a)(ii) carves out, was not read.
