0-20 metres. Good site for snorkellers above the kelp-covered boulders. Bubbles show where gas still rises from this extinct volcano's vents.

Aquatic Life:

Spotties, goatfish, and scarlet wrasses cruise above and black angelfish and demoiselles nest amongst the sea lettuce. Moray eels and rock lobster, including packhorse lobster, live amongst the boulders and Lord Howe coralfish and sharp-nosed pufferfish are often seen. You might notice some scorpionfish have growths from sitting too long near the vents.

Warnings:

This site is in the no-take Tuhua (Mayor Island) Marine Reserve. Enjoy looking and take nothing but photos.
