The group have been summonsed to appear in court at a later date on unlawful hunting charges, Detective Sergeant Rene Rakete, Acting Area Investigations Manager, Western Waikato, said.
But, considering that the country had been in lockdown for almost a month, they may face additional charges.
"We take unlawful hunting very seriously at any time, but this is particularly foolish during the level 4 restrictions," Rakete said.
"Illegal activity involving firearms is extremely dangerous and we will not tolerate it at any time."
