An orca is stranded on Marfells Beach in Marlborough.
Anna McIntosh from Blenheim posted on Facebook asking for locals from Seddon and Ward to come to their aid.
"Please can you spread the word that we need some big burly blokes in wetsuits to help?" she said.
She included photos and a video of several people attempting to help the orca to move out to deeper waters.
Ms McIntosh later updated the status to say members of the Department of Conservation had arrived to help, as well as volunteers from Project Jonah, a charity dedicated to protecting whales, dolphins and seals.
She said the rescue team needed "more manpower" and it was important the orca was moved before low tide.
In her most recent Facebook update, she said "at this stage the tide is now too low to do anything".
"We now just need to wait until the next high tide," she said.
The next high tide for the beach will be at about 1am.
