Well,
New Zealand is stuck in Level 2, until last Sunday, Auckland (our biggest city) was in Level 2.5 (everyone outside of Auckland was equally confused by that, we had no idea there were half measures).
Most of the disease clusters are based in Auckland, there was a petition on-line to build a wall around Auckland.
I had the idea that it should be filled with water afterwards, unfortunately, no-one liked that idea. frown
