I agree with that in its entirety. It's also possible, that those for whom this is an academic and professional exercise will have a different take from those for whom it's a personal exercise (or both).
I'm not sure if there's many New Zealanders for whom it's an entirely academic exercise. I have friends and family in different countries who I would love to see and miss terribly. I'm wildly excited that I'll get to see blood family members in person soon after being physically separated for two years (they are also wildly excited to be able to come). I've also borne the responsibility of supporting an extremely vulnerable/unwell parent alone while my sibling has been stuck overseas (trip cancelled due to bubble closing), which has been hard and I've have seen/felt my sibling's upset at not being able to be there too.
Despite what's been painted, I have a lot of empathy for people frustrated and saddened by the difficulties surrounding travel to New Zealand.
What I sympathise much less with is when those overseas start wildly denigrating the exact policies that have protected their loved ones in New Zealand, criticising the government for not undertaking unrealistic alternative strategies to enable their desire for free travel, and then insulting anyone who applies a degree of logic to their criticisms as "heartless", "brainwashed", "hermits", "totalitarian", "idiots" etc etc.
I understand it's an emotive issue and that people are lashing out. I have friends overseas who've expressed frustrations about it and I've empathised with them, but when I've also expressed my perspective of gratitude for the protection of the restrictions for my health-compromised family members, some of those same friends have been dismissive and rude. That's been really hurtful to me.
I do find a strain of entitlement coming through among some New Zealanders overseas now. I've seen people complaining of feeling like "second-class citizens" without any apparent recognition that the phrase is designed to denote unfairly different treatment for people living under the same circumstances.
The fact is that anyone living overseas has exactly the same rights as a New Zealander that I currently do as a New Zealander but geographical location is an obvious factor in your ability to exercise some of those rights. A young NZ citizen living overseas maintains their right to free education provided by the NZ government but they may have constraints on their ability to access it due to where they live (ie they are limited to receiving it through Te Kura online school).
Likewise NZers living outside NZ's borders but wanting to enter and spend time in NZ may find that this right has constraints on it due to measures implemented to protect the health of the people living inside New Zealand's borders (which they will also benefit from during the time they spend here).
When it comes down to it, I don't believe that one citizen's ability to travel freely to the country of their birth overrules another citizen's right to the protection of their life and health within that country's borders. The government has a core responsibility to protect the lives and health of people living here and they chose a strategy commensurate with that responsibility. It's not come without its issues, but I absolutely believe history will vindicate it, and already substantially has.
