Apart from a few noise complaints, police say members of the public were on their best behaviour hours into the official Covid 19 lockdown.
Officers in and around Auckland reported a fairly uneventful night and early hours of this morning.
"Generally speaking, police were happy about members of the public across the Tāmaki Makaurau region following the move into alert level 4," a police spokesman said.
"One report was received in relation to a loud bang being heard around New North Rd, Avondale, just after 12.30am.
The overall good report in Auckland comes as the country's four-week lockdown began a minute before midnight.
The extraordinary and historic move came days after Prime Minister Jacinda Ardern made the announcement in what she acknowledged is a preventative action - to stop the spread of coronavirus and save lives.
Police, health officials and the Government continue to urge people to stay home.
Police Commissioner Mike Bush gave even more detail about the kind of enforcement officers would take to make sure people were adhering to the rules.
Referring to those who ventured out of their homes, he acknowledged that people can be expected to be stopped and questioned.
"If they've got a good reason - if they're an essential worker or if they're going to the supermarket or if they're going to get food or health supplies - that's fine.
"If not, stay at home. That's how you're going to save lives."
He said officers would have a fair idea of whether or not someone was going to the supermarket.
"We may even have a little drive with you to see where you're going."
