Police say they are "generally pleased" with motorists' compliance at regional checkpoints on the first day of alert level 3 for those outside Auckland.
Officers at Auckland's border south of the city reported limited issues overnight.
"Police were generally pleased with the compliance and most members of our community had the correct documentation ready to show police," said Inspector Kay Lane, of Counties Manukau police.
Authorities are due to release the official number of vehicles that have gone through the checkpoints since the alert level change and those cars that were turned around at the border.
"But we can say the numbers were fairly low and only a small number were turned around," Lane said.
"We are expecting more numbers through the checkpoints today but so far there are minimal wait times."
Freedom has returned, albeit limited, to much of the country but our top expert says New Zealand is not out of the woods yet and hard work is still needed to beat the Delta outbreak.
From midnight, everywhere south of Auckland dropped from full lockdown to alert level 3.
The rules don't change much with everyone still urged to stay home unless leaving is "essential" and travel severely restricted.
The biggest difference is that food retailers can now operate and offer delivery or contactless click and collect.
Thousands of Kiwis have jumped at the chance for their first barista-made coffee in weeks, or a sneaky McDonald's drive-thru for breakfast.
But director general of health Dr Ashley Bloomfield has warned none of us are safe yet from the deadly variant of the Covid-19 virus and has urged a cautious approach to leaving home.
Bloomfield this morning told Breakfast that although positive cases of Covid-19 had started to dip, which was "heartening", they could bounce up again.
That would be expected and mainly because of day 12 results showing up more household contacts testing positive.
However he did not want Kiwis to become complacent.
Bloomfield's call came shortly after a new location of interest was published.
The Crystal Laundromat East Tāmaki, at 186 Te Irirangi Drive in Clover Park, South Auckland was visited by a Covid positive case on Saturday, between 11am and 2pm.
It is the third Crystal Laundromat to feature on the Ministry of Health's website.
A positive case also visited the Crystal Laundromat Manurewa, on Roscommon Rd, on Tuesday August 24, between 11.45am and 2pm.
Crystal Laundromat New Lynn on Great North Rd, West Auckland, was linked to a positive case on Saturday, August 21, between 3.45pm and 4.30pm.
Outside Auckland, people were relishing the opportunity to access food other than what was in their fridge or supermarket shelves.

Today also marks the day where all New Zealanders over the age of 12 can book for a vaccine.
Masks and contact tracing remain mandatory in level 3 and travel outside local areas - and across the "domestic borders" is prohibited unless essential or an exemption is granted.
Police have checkpoints in place to prevent people leaving or entering the Auckland and Northland regions.
Numerous police officers are checking that drivers have essential traffic letters before letting them through.
As of 9.30am yesterday, 2524 businesses had been issued with business travel documentation for movement across level 3 and 4 borders.
Police Commissioner Andrew Coster said checkpoints were in place south of Auckland to stop motorists and to ensure their travel was essential.
He said police had been through the experience before so were well practised and had lanes for trucks.
"Anyone attempting to travel across the regional boundaries separating alert level 4 and alert level 3 areas, should expect to be stopped and asked for proof of essential travel," he said.
The change in alert levels came after 49 new cases, all in Auckland, were reported yesterday, the lowest total in six days. There are now 612 cases in the outbreak - 597 in Auckland, 15 in Wellington and believed to be contained.
Six babies under the age of 1 have caught Covid-19 in the Delta outbreak, Bloomfield said. He said that news was "sobering", although none of the babies were in hospital.
A further update from the Government will be given at 1pm and streamed live on the Herald website.
