Gannets at Cape Kidnappers North Island NZ

[Chipper]

Hi there. Has anybody photographed the gannet colony on the North Island of NZ - at Cape Kidnappers, near Napier? Just trying to work out what focal length lens would be best. Can't seem to find anything on the net.

Only got to look at the images to work out what lenses to take........anything from wide angle to 600 telephoto.
