Two people have been arrested after shots were fired from a car along State Highway 5, near Te Pōhue, on Sunday evening.
No one was injured during the incident which occurred about 5.15pm, a police spokesperson said.
The vehicle was stopped by police as it entered Taupō and two people were taken into custody.
A 29-year-old man is expected to appear in the Taupo District Court on Monday facing firearms-related charges.
The police spokesperson said "there is nothing to suggest the incident is gang-related".
