A "severely dehydrated" wild, orphaned foal has been rescued from a beach in the Far North by showjumping star and author Kelly Wilson.

Wilson was tasked with finding wild horses south of Shipwreck Bay when she came across an injured mare and her foal on a beach near Ahipara on Sunday.

Wilson told Stuff the mare led her off the beach to a bog, where the foal was found in the hills behind it.

Briar Horan/Supplied The foal earned her name, Lioness, for her fighting spirit and the Lion Red beer bottle she drank from.

"The foal couldn't get off the ground. It had probably been there for 48 hours without a mother."

The foal was "severely dehydrated" and had pressure sores on its body from lying on the ground.

Briar Horan/Supplied The foal was helped onto a tarpaulin and then dragged to the beach, before being lifted in Kelly Wilson's ute.

Wilson said it took about two hours to get the foal into her vehicle and back to Kaitaia, where she is staying.

People on the beach helped get the foal onto a tarpaulin, where it was dragged and then carried to her ute.

Wilson camped out with the foal overnight, feeding her and turning her every two hours to try to minimise the pressure sores.

Briar Horan/Supplied The wild, orphan foal was found "severely dehydrated" with pressure sores and ticks all over its body.

Dozens of ticks had also been picked off the foal.

"She's not able to stand yet, but she has a fighting spirit and a good shot of pulling through."

The foal had been named Lioness, partly because of her fighting spirit and the fact she had been given water from the bog using an empty Lion Red beer bottle.

Lioness was estimated to be aged between six to 10 weeks old.

Wilson said it was likely Lioness' mother was dead, as she could not be found.

She is being monitored by a vet who is happy with her condition.

Briar Horan/Supplied The foal was fed and turned every two hours overnight to try and minimise its pressure sores.

If the foal pulls through, it would be going home with Wilson to her parents' farm in Hukerenui.
