Immigration NZ meet their legal obligation to protect personal information by randomly rounding totals in the tool base three. This is best practice from Stats NZ. It does mean figures can be different to their previously published data.

As part of Immigration NZ continuing work to unify the data available in the Migration Data Explorer, they have renamed some application criteria that appear in the Population dataset. In particular:
The Resident Global Impact Visa application criterion is now named Global Impact.
The substream for the 2021 Resident Visa has been changed from 2021 Resident Visa to Skilled.
The substream for the Global Impact Visa has been renamed from Entrepreneur Category to Entrepreneur. This groups it alongside other application criteria that allow residence for entrepreneurs, such as the Entrepreneur Category and Entrepreneur Plus Category criteria.
The substreams Humanitarian and Humanitarian/International have been merged with the International/Humanitarian substream.
