A union is worried that some major takeaway outlets could breach Covid-19 alert level 3 restrictions, with their plans to serve customers next week.
Unite Union spokesman MIke Treen said he has been in touch with McDonald's about training photos, which appear to show food passed to drive-through customers, closer than 2 metres away.
However he said Wendy's seems to have a good plan.
"Not requiring expensive solutions, just putting a small table outside the drive-through window and keeping the respective windows shut, the other one was shut while their own window was open."
He said the Wendy's video demonstrated social distancing and the fact that no cash transactions are allowed.
Treen said the union will be monitoring outlets next week to keep its members safe.
Restaurants and cafes will be allowed to open under alert level 3 if they can provide contactless payment, pickup and delivery, and staff can keep one metre from each other.
RNZ has sought comment from McDonald's.
