Police will be setting up checkpoints around the boundary of Auckland following the city's move to level 3 lockdown on Wednesday.
Police Commissioner Andrew Coster said nine checkpoints at exit points just inside regional boundaries would be established.
Five of those checkpoints would be located in the north and four will be in the south.
In the north, the checkpoints will be at:
- Twin Coast Highway/North of Coal Hill Rd
- Blackswamp Rd
- SH1 North of Twin Coast Discovery Highway
- Twin Coast Highway/Cames Rd
- Twin Coast Highway/Ryan Rd
In the south, they will be at:
- Mill Rd
- River Rd/Lapwood Rd
- Kawakawa/Orere Rd & Orere/Matingarahi Rd
- Matingarahi Rd/Lyon Rd
The country's largest city went into lockdown at midday, following the confirmation of renewed community transmission of COVID-19.
The rest of the country moved to alert level 2.
Prime Minister Jacinda Ardern in announcing the lockdown on Tuesday evening said Auckland would be defined by the boundaries of the Super City.
Coster said the checkpoints would be similar to those implemented over long weekends during the previous lockdown.
"Police will have a visibly higher presence across the region, with all three Tāmaki Makaurau Police District Commanders working together to respond to the regional alert level 3," Coster told media on Wednesday.
"We will be visible around supermarkets and places where communities need the assurance of police presence."
He said the focus would be on educating people and ensuring they are aware of the new restrictions.
"We will be questioning drivers to make sure the travel is essential," he said.
"If people want to avoid unnecessary delay then bringing the best evidence they have of their place of residence will enable them to pass through smoothly."
He said it was "quite possible" the checkpoints would be implemented from Wednesday but police were still "working through the details".
Coster said he was "absolutely confident" police had identified the best places to control flow in and out of the city, though admitted police were still "relying on people to do the right thing".
"It's hard to make a large city hermetically sealed so ultimately we need people to buy in and do the right thing."
Although initially the checkpoints would be staffed by police officers, Coster said it was possible they would have assistance from the Defence Force in the future.
