for details of our government's advice.
The
advice starts off saying "
We currently advise that all New Zealanders do not travel overseas at this time due to the COVID-19 pandemic, associated health risks and widespread travel restrictions".
If you continue reading, the next paragraph says "
If you choose to travel overseas despite our advice, our individual destination pages remain an essential of source of information on specific risks"
It is important to understand that the advice against travel is general advice for citizens and residents but is not a regulation or law. The advice is given to signal to people who are currently in ANZ that they are safest to stay put here in ANZ but if anyone does choose to travel then they should not expect consular assistance if they get into difficulties.
People currently in ANZ are free to travel at any time to anywhere they like without needing to ask for permission or checking with anyone beforehand.
People travel out of ANZ everyday for all sorts of reasons.
Of course, getting back into ANZ is a different matter. There are regulations and laws covering who can enter ANZ, where they can travel from and what they are required to do when they do eventually get back to ANZ. In this area the website seems to have the correct information.
Interestingly, the website suggests that people travelling from ANZ to Spain do not need to have a recent Covid test.
