An Auckland security guard was assaulted after a woman refused to wear a face mask at a supermarket.
Police say the woman became "aggressive" at the security guard when offered a mask.
The woman allegedly punched the security guard at the Takanini Pak'nSave.
The security guard was then chased by two men with weapons.
Police were called and arrested two people in a nearby area.
A 26-year old woman has been charged with assault and was issued an infringement for failing to wear a face covering.
A patched Black Power member was also charged with assault with a weapon.
Both are expected to appear in the Manukau District Court at a later date.
Police remained at the Pak'nSave, conducting reassurance patrols and support for the security guard.
Police say there is no tolerance for such behaviour towards essential workers.
An Auckland-based woman was also arrested after being found in Whangārei.
Initially, the woman was turned around at a checkpoint trying to leave Auckland but allegedly travelled on private property to avoid the checkpoint.
The 33-year-old has been charged with failing to comply with the health order and is due to appear in the Whangārei District Court this month.
A number of people have also been caught flouting rules at Auckland's northern and southern boundaries.
On Monday, a man tried to enter Auckland claiming to collect a prescription from a pharmacy.
Police found that was not true and the man was refused entry.
A 25-year-old man found to be in breach of his bail conditions when stopped by police on SH1 in Kauri.
He had driven through the northern checkpoints from Auckland and into Northland after allegedly claiming to have changed his bail conditions.
He was charged with failing to comply with the health order and will appear in court next month.
