TURTLE tagging is a central activity in the recovery plan of sea turtle populations.
WWF South Pacific marine species co-ordinator Laitia Tamata said tagging took two forms — satellite and flipper tagging.
Mr Tamata said for satellite tagging, it showed which country turtles came from, their migratory route and why they were headed a certain way.
"The accumulation of data from satellite tagging will then inform us on why they are choosing a particular destination, particularly for foraging grounds that will give hot spots for conservation," he said.
"We've done this with the maps produced in 2010 which I presented in New Orleans.
"On the other hand, for flipper tagging, the most important information we are able to capture is the growth rate of the turtle is recorded — species of turtle, carapace length, width and the tag number, and place it was released."
