Between 1979 and 1998, 6975 Arctic waders of seven species (mainly Lesser Knots Calidris canutus and Bar-tailed Godwits Limosa lapponica) were caught by the Miranda Banders and the New Zealand Wader Study Group near Auckland. Of these, 1375 were marked with a white leg-flag on the tibia to denote capture in New Zealand. Thirty-two Lesser Knots and three Bar-tailed Godwits had already been banded overseas, mainly in Australia. Another two Lesser Knots and two Bar-tailed Godwits banded overseas have been found dead in New Zealand. Up to 135 Lesser Knots, 34 Bar-tailed Godwits, 2 Turnstones and 2 Red-necked Stints (Calidris ruficollis) bearing Australian leg-flags, and 2 colour-banded Bar-tailed Godwits from Alaska have been seen in New Zealand. Of those birds banded or leg-flagged in New Zealand, up to 21 Lesser Knots, up to 17 Bar-tailed Godwits, and two Turnstones (Arenaria interpres) have been recovered or seen in six overseas countries. One Turnstone banded in New Zealand was caught in Australia and then recaptured back at its original banding site. The migration routes taken by Lesser Knots, Bar-tailed Godwits and turnstones visiting New Zealand have been deduced from these band recovery data.
