A scene examination will take place following an armed offenders squad (AOS) callout in Horowhenua on Saturday night.
Guards have remained at a Cook St address in Foxton after reports shots had been fired.
A dog squad and the AOS were dispatched just after 7:30pm and roads around the area were cordoned off, with some traffic on State Highway 1 diverted.
Police are speaking to two people who they say are fully co-operating. Initially police said the two people were in custody, however they later clarified the duo were not under arrest.
No one else is being sought in relation to the incident.
Palmerston North police are asking anyone who witnessed the incident to contact them.
