A 33- year-old man has been arrested and is currently speaking to police.
Police were called to the suburb of Phillipstown just after 3pm today and set up a cordon.
Police said there was reports of "suspicious items" at a home on Newcastle Street and a NZDF Explosive Ordnance Disposal team had "rendered the package safe".
Police lifted the cordons from the area about an hour later and residents were allowed back home about six o'clock.
A no-fly zone was put in place over the area.
