From the Wikipedia article

Air New Zealand Flight 4374 was a flight from Gisborne which crashed while landing at Auckland in poor weather, killing two of the four people on board.

Crash and rescue

At 14:28 the aircraft had descended to 3000 feet and the pilots deployed the flaps. The aircraft's speed was 165 knots, and increased to 211 knots; 2 minutes 14 seconds later the aircraft crashed into the harbour 1km west of the intended runway, killing two, the captain and a passenger. At the time of the crash, Auckland was experiencing its heaviest rainfall in 43 years, and the visibility was officially described as "restricted".

An Air New Zealand Boeing 737 aircraft which departed 2 minutes after the crash attempted to alert the control tower about the accident. However, the controllers denied that they were alerted.

Two survivors were found supporting themselves on the tip of the aircraft fuselage and were rescued by navy divers in two rubber inflatable Zodiac boats. Rescue efforts were hindered due to strong rips in the harbour. The two survivors were taken to Middlemore Hospital. Captain Circuitt's body was freed by navy divers around 3.5 hours after the crash, whilst engineer John Forbes's body was recovered later that night. At the time of the accident, Auckland Airport's rescue hovercraft was undergoing an overhaul and was unable to serve the downed aircraft, further hindering rescue efforts. The hovercraft was also known to be unreliable, sparking discussion on the airport's rescue response and safety.

The aircraft wreckage was recovered through the use of inflatable bags, floating the wreck back to shore.

Investigation and cause

Investigation

The aircraft's flight recorders (black boxes) was recovered and sent to Melbourne for investigation by the Australian Ministry of Transport Air Safety Investigation Branch.

The investigation found that the crew were likely misled by a visual illusion due to a rain shower obscuring the runway threshold during their base turn. This, coupled with a failure to monitor their flight instruments effectively due to the pilots believing they were at a safe height, caused the aircraft to crash into the harbour.
