Some amazing things are going on in the Taputeranga Marine Reserve of Wellington's south coast.

Over the weekend, a small team of divers from Niwa and Ghost Fishing NZ were treated to a rare sight – hordes of female crayfish marching to the edge of the reef to release their eggs into the current.

Ghost Fishing NZ project manager Rob Wilson spotted the spawning crayfish during a previous dive on the edge of the reef and decided to go back and get it on camera.

Alongside an "awesome crew" made up of Niwa scientist Serena Cox and technical divers Rob Edward and Franz Ombler, Wilson ventured out into the reserve by sea scooter.
