Police conducted an armed vehicle stop on State Highway 2, near Waipukurau, and a person of interest was spoken to.
"Shortly after, police cordoned off an address of interest in Waipawa, and a nearby kindergarten was placed into lockdown as a precaution.
"Police later spoke with the sole occupant of the address where it was discovered that fireworks had been let off at the address, and, given the built-up area, they could have easily been mistaken for gunshots."
The occupant of the address was reminded of the inconvenience this has placed on the people of Waipawa and for him to save his fireworks for November 5, she said.
"No arrests have been made and police are not looking for anyone else."
Police thanked the people of the Waipawa community for their patience and understanding during the incident, especially those people on State Highway 2 who had to stop and witness police conducting the vehicle stop.
