In any case, in what meaningful sense are the majority of us currently "locked down"? I've just looked up the Stage 3 guidelines and there is nothing in them which stops me from doing what I want/need to do.
I can see there are still some restrictions on large indoor gatherings, but there aren't many. Supporting those people and businesses who still can't operate normally should be manageable.
I shall continue wearing a mask indoors for the foreseeable future because it seems a sensible thing to do. I shall avoid anywhere which is not well-ventilated. We now know that the biggest risk for transmission is prolonged contact with infected people via airborne transmission. The aerosol effect means that infected particles can linger in the air for some time and the risk increases in overcrowded poorly ventilated indoor spaces, such as schools, private houses, some offices and pubs. Not surprisingly, that's where most transmission is happening.
An announcement is due to be made on Monday and any speculation at the moment is premature, although probably not unexpected.
