I am an Indian Citizen holding a Green Card. I plan to apply for American Citizenship, and I have to renounce my Indian Passport when I do that.
The thing is, I am a permanent resident in New Zealand and I can live/work in New Zealand Permanently and indefinitely. When my Indian passport is cancelled, my Indefinite NZ visa will also be cancelled! How can I travel to NZ?
(NOTE: The OP updated their question to state they are a PR in NZ so this answer no longer covers the question asked. As there is no other answer, and there is useful information in the comments for this answer I'm not going to delete it - but the answer isn't isn't valid after the edits as it is referring only to a NZ tourist/business visa, not a PR)
As a US Citizens you will not require a visa to travel to New Zealand for stays of up to 3 months.
You will need to apply for an New Zealand Electronic Travel Authority (NZeTA) once you have received your US Passport, and then you will be able to travel to New Zealand without the need for a visa.
If it is a permanent resident visa without conditions, your visa should not be cancelled even if your nationality changed and your passport is cancelled. But you will need to apply for a transfer of eVisa with details of your new, valid US passport.

A change of nationality does not create a deportation liability (fraud, forgery, character, crimes, security etc.) nor form any ground to refuse entry permission (provided the visa is transferred).
