Police also executed a search warrant at an address in Havelock North on June 1, where two firearms and a large amount of ammunition were seized.
This resulted in the arrest of a 20-year-old man on multiple firearm-related charges. He was due to appear in Hastings District Court today.
“We hope these arrests provide reassurance to the community that we work hard to keep our communities safe,” said Detective Senior Sergeant James Keene.
“Police will continue to target unlawful firearms in the possession of criminals.”
He said police encouraged anyone who had concerns about organised crime, criminal activity or the illegal possession of firearms to get in contact.
