Extra Police are on patrol in Levin after several firearm-related incidents in two days.
Manawatu Area Commander Inspector Ross Grantham described recent shooting events in the area as "brainless violence" that put people at risk of harm.
Police are investigating several reports of shootings in the area, including a man who presented at a healthcare centre with a gunshot wound to his thigh. He was transferred to Palmerston North Hospital in a serious condition and enquiries are ongoing.
"Events that involve firearms are extremely concerning and we aren't wasting time to find those responsible. We have put additional officers on patrol, but we need to hear from anyone who has any information that may help."
About 8.55pm on Monday, Police were called after a firearm was discharged from a vehicle on Hinemoa Street, hitting a house. Thankfully nobody was injured, but the occupants and neighbours were shaken by the event.
A scene guard remained in place overnight and a scene examination is ongoing today.
Shortly after 6am today (Tuesday), five shots were reported to have been heard on Mabel Street. Police located a shed that appeared to have been shot and a scene examination is ongoing.
Inspector Grantham said investigation teams were making a number of enquiries and urged anyone with information to contact Police.
"There will be a visible Police presence while we complete scene examinations and speak with neighbours and those involved. At this early stage, we are still working to determine what firearm was used in the shootings targeting properties, and we don't yet know why this happened.
"It's brainless violence that puts people at real risk of harm and we are focused on finding those involved. Levin's a caring community and people don't want violence like this in their town. We know this will be unsettling, and the additional officers who are on duty will be carrying out patrols across the town.
