We have a similar system is AU. It’s not really enforced all that well. But most people cooperate and life is generally back to normal. You also only need to do it in enclosed areas like shops. Mask wearing is still mandatory on public transport. Unfortunately very low cases doesn’t mean the virus is gone. Occasionally there is a case and if you want to clamp that down as fast as possible, you need contact tracing. Which means we need to know where you are. For most people, no extra information is being leaked. Facebook and google already know where they are and they are far more malicious than the AU or NZ government. The tin foil hatters like you can take extra measures I’m sure. The US has over 25million cases and over 400k dead. That’s literally the entire population of Australia infected. So I’d argue that NZ and AU are objectively better and we shouldn’t worry about “overreach” just yet.
