A rare visit from a seal normally only seen in the Antarctic prompted safety warnings for beachgoers in an upmarket Auckland suburb yesterday.

A leopard seal about 2m long was spotted on a sea wall at Home Bay, near Herne Bay.

Soon after the sighting was reported, the Department of Conservation issued a safety warning, urging people to keep their distance.

"It's possible the seal sighted this morning at Herne Bay is the leopard seal seen at Kawakawa Bay last month," said DoC Auckland area biodiversity manager Phil Brown.

"Leopard seals are bigger and more aggressive than New Zealand fur seals and we are warning the public to ensure they stay safe by keeping well away from any seals they see in the Auckland area."

Mr Brown said anyone encountering a leopard seal - or any seal - should keep at least 20m away and not disturb them.

"Leopard seals can be aggressive if agitated and while they can appear docile resting on shore, they can lunge powerfully and quickly," he said.

"If a leopard seal is basking on the beach or swimming around in the sea and is fine then people should just leave it alone.

"People should never get between a seal and its access to water."

Reader Robin Tulloch contacted the Herald after coming across the seal while out for a walk with her dog.

"I noticed what looked like a banana-shaped log. The dog didn't notice it at first as she was sniffing around on the grass on top of the sea wall.

"The dog then jumped and looked at this log from directly above and I became aware that perhaps it wasn't a log," she said.

"I tied the dog up and stood directly above it. It was a large seal. It had a white underbelly and a sleek face like a snake. No ears.

"It had spots around its neck and under jaw. It was at least two metres long. It appeared to be healthy. There were no visible injuries on its grey/green body.

"It looked at me with large eyes [and] opened its mouth to show a row of teeth. It then turned over in the sand and using its flippers entered the water and swam away out into the bay. It surfaced well out into the channel. I saw it surface once and then it disappeared.

"A startling start to my day and a wondrous experience."

Mr Brown said leopard seals had long, slim bodies, comparatively large fore-flippers.

"The disproportionately large head, massive jaws, impressive teeth and tremendous gape give them a snake-like appearance.

"It's rare for a leopard seal to make it as far north as Auckland as they are normally found along the edge of the Antarctic pack ice."

Mr Brown said the seal spotted yesterday was probably a lone juvenile male.
