A small plane has crash-landed in the Mapua Estuary, near Nelson.
The two occupants have emerged with minor injuries after emergency services were called to the incident at 10.30am.
Fire and Emergency shift manager Andrew Norris said a float plane landed poorly in the estuary, also known as Waimea Inlet.
He said the plane started to sink, but everyone was rescued and the aircraft was towed ashore.
Police were investigating, Norris said.
