Dunedin Airport has reopened after a suspicious package turned out to be a hoax.
A New Zealand Defence Force explosive ordinance team "neutralised" the object, believed to be a bag, and the scene where it was found has been secured.
Police are now investigating who left it there.
Two flights were cancelled Monday morning - one to Auckland and one to Wellington.
An Air New Zealand spokesperson told RNZ the 301 customers affected would be placed on different flights on Monday.
In the aftermath of that incident, police in Auckland responded to a bomb scare at a train station in the CBD after somebody left luggage unattended.
Defence Force personnel carried out a controlled explosion of the bags as a precautionary measure on Friday night.
