McDonald's is standing by its safety processes after Wendy's New Zealand chief executive Danielle Lendich criticised other fast-food giants.
At the lowered alert level, Kiwis can get their fast-food fix, but only if it can be ordered and picked up without face-to-face contact.
There had been 1035 complaints about businesses breaching level rules, most about physical distancing, Prime Minister Ardern said at the daily update today.
There were 185 breaches of under level 3 - 46 had been prosecuted, an increase of 21 people in 24 hours.
And while McDonald's was not specially named by Lendich, it was operating its drive-thrus for customers.
"I have to say when I saw the other big players operating just about, as usual, I was quite shocked," she said.
"I think everyone should just abide by the rules ... the Government was quite clear - they did say drive-thrus could operate but it's supposed to be contactless."
When asked to respond to the comments, a McDonald's spokesperson Simon Kenny told the Herald they had none to make.
However, Kenny said the restaurant was standing by previous comments on how they were operating during alert level 3.
McDonald's sought advice through official Government channels and had third party auditors review its level 3 plans before opening.
Staff had been trained on new processes about how to receive and return cash with minimal contact, how to hand over receipts and not to put straws in drinks.
Sales and point-of-sales areas would be washed hourly at a minimum and cash would not be handled at the same window food was given out.
"The number one priority for McDonald's in planning to reopen under alert level 3 is the safety of our staff and customers," Kenny said earlier this week.
Lendich thought it was key for people and businesses to obey the guidelines set down by the Government in order to get down to alert level 2 as soon as possible.
Food outlets which did not follow the level 3 guidelines could be dealt to by the Government, Prime Minister Jacinda Ardern said.
The payment process was contactless, with an eftpos machine outside and paywave available.
Customers also had to keep their car window up and could not put it down until orders had been placed onto a table and Wendy's staff closed their window.
Staff were keeping one metre apart from each other and were regularly washing and sanitising their hands, even sitting at separate tables on their lunch breaks.
Fast-food restaurant businesses were allowed to be open during the lowered alert level but only if it could be ordered and picked up without face-to-face contact.
McDonald's
Macca's drive-thru was open and so was its delivery service, McDelivery, but only with a limited menu at 137 of its 170 restaurants.
They were working to extend their limited menu but due to limited stock supplies, it could take some time before they were back to normal.
Staff were required to wear gloves, observe safe distance markings and the number of staff in-store at one time was reduced to allow for more space.
