Never Fail Rock - GMI - Goat Island & Hauraki Gulf

Rainbow Wall is a bit of a journey out, tucked away near Rendova Island, but it consistently delivers. We love a good wall dive, and this one doesn't disappoint, dropping quickly into the blue. It's a spot for when you're feeling confident, perhaps a bit more advanced in your diving, because the currents can be lively. We’ve hooked in here more than once, just watching the show unfold – big schools of Blue and Gold Fusiliers streaming past, then a sudden flurry of Manini, and the occasional Malabar grouper lurking in the crevices. The real draw here is the open water. Keep an eye out into the blue, because that’s where the action happens. We've seen eagle rays glide by, their shadows passing over us, and it's not uncommon to spot a shark cruising the deeper sections. It’s a site where you spend as much time looking out as you do at the wall itself, which, by the way, is covered in some lovely corals and home to plenty of vibrant Lineated and Latticed Butterflyfish. Visibility averages a solid 22 meters, which helps you appreciate the scale of it all. This is our pick for divers who crave that wide-open ocean feel and aren't afraid of a bit of current to get the best views.
