But how does that keep SARS-CoV-2 out of the country?
A negative test can mean:
* False Positive
* Too early in infection to test positive
* Actually have no SARS-CoV-2 in body.
In some ways better not to test and put people in isolation, as if people are option 1 or 2 they will think they are fine and go a spread SARS-CoV-2 everywhere. Which is the opposite of what you want.
Tests are only helpful when test at the right time and fully understand what the results could mean.

There are plans to add the Pacific to our bubble and they are even more risk adverse due to their health infrastructure. So given that risk profile we have to been along those lines as well.
Also getting the stats to back the percentage up, will be ethically hard. Would be hard to get ethics approval to expose a group of people to SARS-CoV-2 then perform a test every X hours to see how long between exposure and detectable tests. Then also test at different exposure levels and track that over time. Currently it seems to be days between exposure and tests returning positive. (Going from household close contacts will often test negative when the index case is symptomatic and has tested positive and those household close contacts will later test positive).

NZ is working towards a zero tolerance outside of border isolation and quarantine, so I don't see that working. If the goal is keeping out most imported cases it would work.

I think opening to other countries would be more worthwhile than the Pacific if one precluded the other.
Deliberately exposing people definitely seems untenable, in most countries at least. There is so much testing and so many studies done around the world that there should be some reasonable statistically accurate inferences drawn from naturally occurring cases. The NBA for example is thinking that three days should be long enough for detection to be accurate enough after one player tests positive to be confident that others are negative.

That seems overly stringent.

What sports are doing I would be careful to read too much, as they will be putting in other controls in place. Like having some type of team bubble and minimising contact with others. That is also three days from a positive test but the other team mates would have been exposed daily to that person in the infectious period before the test so they themselves may be nearer a week+ from initial exposure by that point.

Yes, I am aware of that. My response was based on the original post which said: "By regular I mean, we won't be going through 2 weeks of quarantine etc when we arrive back in country. Back to 90% normality of travel." I don't see that happening for a very long time for flights from the USA to NZ. And for people like me who live in the USA and who do not hold a NZ passport, there simply is no realistic possibility of flying NZ1/2 between AKL-LAX in the foreseeable future.

That's not quite accurate 
The PCR test tends to give more false negatives and almost zero false positives. The main reason is how difficult it is to get virus from the swaps if a person's infection is relatively mild. Anti-body testing will usually give more false positives than negatives--which is why for things like HIV an ostensive antibody test is followed up to see if there's an actual active HIV infection.
This is why the NZ stats are for confirmed and probably cases. Someone exposed with the symptom profile might test negative and still have COVID.

The PCR based testing protocol which is the current method for identifying SARS-CoV-2 in samples, is possibly too accurate as the most recent positive from the Marist cluster they believe the person had actually recovered from COVID-19 and was the remaining RNA fragments from a weeks recovered infection.

Historically, my travel to DUD and MEL has been for work, but my travel to RAR and LHR has been for pleasure. I have every intent to resume travel as much as I did before, but time will tell. Quite frankly, I'm getting more and more disheartened at the thought of being stuck here in the USA without the chance to get away on a regular basis.

But I am sad that, as I am "trapped" in New Zealand, we don't have the same variety as the USA. You have such a huge variety of cultures and entertainment options. So your domestic travel can be extremely varied. Here, it's mostly pretty similar, even if it is beautiful.

There is only some many things / places you can go in New Zealand. With Jetstar not currently flying we’re stuck with NZ running the show.....
I would expect the Tasman demand is going to be massive once the Tasman reopens. Hopefully will get the 787s some passenger work.

I am very glad we got the virus under control because mg parents are older and they are the most important thing.

I just want to clarify that this is most definitely not a criticism because even before this meltdown existed, we visited family almost every year and I/we loved every single minute of it (well apart from Queenstown over New Year, too many people for me!

Logically its when a vaccine is available and can be rolled out to the NZ population. There is a a massive international effort underway with over 100 in development and Trump making it clear the funds and resources available are unlimited, with manufacturing on mass of multiple candidates so that the right one is ready to go as and when it works. But when could that be rolled out accross NZ - at least a year from now absolute best, and that's if all goes really well.
But what does NZ do if there isn't a vaccine next year or the year after that? The global population slowly gets infected, but NZ is untouched. Maybe testing becomes super accurate, or some sort of immunity passport, or therapeutic treatment.
Personally, I think a viable vaccine and excellent treatments will be available this year. Or the virus might fizzle as some suspect now that it has infected the most vulnerable.

It's true it isn't guaranteed but given how many resources are being poured into it, I would be betting on it rather than not.
By betting on it, our domestic market is relatively back to normal. These past two days have been honestly almost back to normal from what I have seen. Obviously it's now modified and some stuff is a no go (large events) but it mostly feels normal now that we are in level 2. And we got to this stage super quick due to the "elimination" strategy.
Another country would be in the same position as us, but on a much bigger scale: China. Its barely gone through their population of 1 Billion!
