Watch: Kind-hearted rescuers help dolphins trapped in shallows of Wellington's Houghton Bay

Good Samaritans have come to the aid of two stranded dolphin's caught in the shallows of a Wellington bay.

Melissa Prowse told 1 NEWS that she was watching a large pod of around 50 dolphins from a clifftop between Princess and Houghton Bay yesterday morning around 10am when about 20 of the mammals swam in to feed on a school of fish in the shallows.

"We saw most of the dolphins leave but then heard heaps of splashing and saw the two dolphins visibly stressed stranded up on the rocks in the shallows," Ms Prowse said.

Three people Ms Prowse was there with, her brother Daniel Prowse, partner Zane Burn and friend Hanna Van der Giessen sprang into action racing down the cliffside to free them.

"We were so happy that we were in the right place, at the right time, as they might not have been seen otherwise!" Ms Prowse said.

Video of the incident posted to Facebook shows the rescue take place with the dolphins swimming out to safety.
