Some more wording changes. Most people will go 'who cares'. But I find the changes to wording interesting as they plug holes and so on :)

Alert level 2 and other pages From:

We encourage you to wear a face covering when you cannot maintain physical distance from others.

You legally must wear a face covering if you are aged 12 or over when:

We encourage you to wear a face covering when you cannot maintain physical distance from others. If you are around people you do not know, it is a good idea to wear a mask. Face coverings stop droplets spreading when someone speaks, laughs, coughs or sneezes. They are a way we can protect outselves and each other.

In some situations, you legally must wear a face covering if you are aged 12 or over. For example on public transport, inside retail businesses and public venues.

Doing Business under lvl2 has some additions to clear up (most I've dealt with have basically chosen to go this way anyway..) and travelling suggests flexible times to outside peak 

To help achieve physical distancing, customers are not permitted to stand on public transport. Talk with employees about changing their work hours or if they can work flexibly, if possible.

If your workplace is not open to the public — for example, an office or a factory floor, workers only need to keep 1 metre apart. There is no limit on the number of people that can be on the workplace premises, as long as everyone can safely physically distance. Your employees do not need to wear a face covering, but we encourage everyone to wear one.

If you have visitors to your workplace, you need to make sure they keep a 2 metre distance from others — for example, reception staff.

Coverings in the same section has been broadened a little..

• in a customer-facing role in a hospitality business, for example cafes or restaurants
• in a customer facing role... (at a retail store)
• Venue vs facility

Similar on level 4 guides, and adjustments for limited public transport (no standing on busses)

Some interesting amendments to lvl3 for general public. Cutting out the text that seemed to OK 2-family mingling when you dug deeper and clearing up what keeping your bubble small means.

At Alert Level 3, you legally must stay within your household bubble whenever you are not at work or school.

Your household bubble is the group of people you have day-to-day, physical contact with. At Alert Level 3, it includes the people you live with and, if necessary, close family, isolated people or caregivers. You must keep your bubble as small as possible.

You cannot invite friends, whānau and extended family who are not in your bubble to your home.

And spelling out why masking is recommended. As with other pages

Sporting under level 2 changes..

You do not need to wear a face covering when participating in team sports. Has been added
