Associate Health Minister Peeni Henare is calling on whānau to comply with the alert level 3 restrictions.
It comes amid protest action over the Government's COVID-19 response.
Around 150 unmasked protesters gathered in Auckland's Aotea Square on Saturday, despite the re-emergence of community transmission in the region.
During an interview with Three's The Hui, Henare was asked about the role of social media in helping to organise protests and spread misinformation about the virus.
He says Māori ministers are working hard to counter these messages, and wants Māori social media users to act responsibly.
"Be mindful of what you share, knowing full well that by sharing kōrero - whatever it might be - it grows a bigger audience".
Henare says if whānau have questions about coronavirus they should talk to local health providers and community leaders.
"Listen to the experts on these matters… They have the best information to provide to our whānau".
Māori health advocates want the Government to increase the visibility of Māori leaders in its COVID-19 response.
Henare says while he is mandated to speak about COVID-19, he hasn't been able to appear in the daily press conferences alongside Director General of Health Ashley Bloomfield.
"Sadly living in Tāmaki Makaurau means I can't leave Tāmaki Makaurau… But we are doing our best where we can to continue to represent the views of our people."
