This weekend I got my PADI diving qualification at Poor Knights in New Zealand.
There were loads of fish and we had a brilliant instructor who made everything very simple. We dived at Blue Mau Mau Arch, Nusery Cove and Gentle Forest. Blue Mau Mau Arch was amazing - just like those TV programmes on fish. Nursery Cove had loads of infant fish, hence the name.
It was 17 degrees C in the water, but I didn't find it too cold after the initial shock of jumping in.
