That is amazing!! The best glow worm that I ever seen in New Zealand! The spot is the first cave at the right side of the beach. You can go walking. FyC

We could have managed to find the cave eventually after peeking in all the others littered all over the coastline. Instead of finding glowworms we found an entrapped Seal in the bottom of the hole tangled in fallen tree branches. We scared each other like hell. We removed the branches and logs got stuck in there and let him a safe way to leave with the next high tide. It was an amazing experience and scary a bit.
