If anyone missed it, and I did miss it until I watched TVNZ news tonight, there have been new rules announced today under level 3 for people over 70. In level 2 and up, people over 70 and people at risk had to stay at home, and couldn't go to the supermarket etc. But under level 3, they will be able to go shopping to the supermarket or to work, and it doesn't appear there are now any restrictions, except to be especially careful.
I don't believe it was ever mandatory for over 70s etc to stay at home, it has always been on a strongly advised basis.
I think it was initially a requirement, but I don't think it was actually being policed. But I think they then changed the wording to 'encouraged to stay at home' at some stage more recently. I have noticed that things get tweaked on that website all the time and it all seems very fluid.
But I do know that before lockdown one supermarket did send an email out to customers saying that people over 70 need to stay at home as per the government directive, and would need to get someone to shop for them or use online shopping. This was their reasoning for not having a dedicated time for elderly shoppers to get their supplies, as it would be in conflict with the governments directive for people over 70 being directed to stay at home. But the other supermarket crowd did setup dedicated shopping times for the elderly. No wonder though people are confused by it all.
