Of the alert level 3 breach notifications, six were about a business, 17 were about a gathering, and three were about a person.
Most of the reports WorkSafe received were about Auckland-based businesses, followed by Christchurch, Hamilton and Wellington. The region with the fewest reports referred to WorkSafe was Gisborne.
"For the most part, people are wanting to do the right thing in these challenging times, and we really commend those taking the right steps. Our approach has been first and foremost about educating those we receive complaints about and working with them to put safe systems in place to support their staff and their communities," Nalter said.
"Where we can't get this level of co-operation, and there are people deliberately flouting the rules and not displaying the right level of care, businesses can expect WorkSafe to consider enforcement".
Nalter said it was each business's responsibility to ensure they were legally able to operate under the different levels.

He also reminded businesses to ensure their alternative contract tracing systems for people who did not have the QR scanning app were easily accessible and to have record keeping in place for their staff as well.
"Get creative with implementing systems to encourage suitable physical distancing. Look at how the layout of your premises can be adjusted to best facilitate this."
