Shark scientist Riley Elliott is calling on the public to help find a missing shark tag.

In a post on Facebook, Riley says the tag appears to have floated ashore and has been tracked to Gate Pa, probably taken home by a resident who may not be aware what it is.

'This isn't a manhunt it's a tag hunt,” says Riley on his Facebook page.

He was able to use satellite help to locate the tag within a few kilometre radius.

'The person likely doesn't know what it is, so please if you know people in the Gate Pa area or a community page there, please share this post and see if we can get the tag back.”

He is offering a reward of $100 to anyone finding and returning the tag.

On Monday Riley asked the public to keep an eye out for the tag along Papamoa beach.

'Unfortunately the famous Great White Shark Daisy seems to have dropped her tag and it has floated inshore onto the beach roughly in the area in front of Papamoa Beach Surf Club.”

The last recorded location for Daisy was from the last signal from where the tag came off which Riley says was 'just along the southern shore of Matakana Island, before the tag – with no Daisy – drifted in the wind down the coast and washed ashore in Paps”.

'There has been so much debris in the ocean from the ongoing floods that these tags have had a hard ride through the usually empty ocean, and this is the third to pull from the sharks.”

The tag looks similar to the above picture.

'It will have seaweed growth on it so may blend in.”

The last location he had on Monday showed the tag on land 'but the last location signal was an inaccurate one, so it's within a few kms of this area, but definitely on the beach as it washed ashore”.

He says the satellites were not overhead to give more accurate locations until Monday night.

On Tuesday he posted that the tag 'seems to have been picked up and taken home/to work by someone”.

He thinks that it is likely the tag has been found by someone walking along the beach at the high tide mark.

Riley asks anyone who has found the tag to text or call him on 027 463 7397.
