A man arrested following a fatal shooting in Waikato has been charged with possessing a newly prohibited military-style semi-automatic rifle.
He also faces a charge of possession of methamphetamine for supply.
The man was charged after an incident involving four men, one of whom was killed. The others were injured.
The three injured men, who remain in Waikato Hospital following the shooting, have also been arrested and charged with aggravated burglary.
Police said a forensic autopsy was being undertaken on the victim and he had yet to be formally identified.
Officers are conducting scene examinations at several locations in the Kawhia area.
"Police would like to reassure people that there is no risk to the community. No one else is sought in relation to this incident."
Detective Inspector Graham Pitkethley said yesterday that officers were called to a rural address about 4am yesterday after reports four people were shot.
Locals told NZME the incident started at a property south of Hauturu School, about 20km south of Kawhia. Four people then got into a Toyota SUV and drove to the school for help.
It remains unclear if the school staff member or another person then called police for help.
The police crime scene investigation stretched about 10km and involved three separate properties including the school.
Two vehicles appeared to be under investigation, including the Toyota which was parked up at the school with its back window smashed out.
