A group of nearly 20 people has ventured onto the closed Whakaari White Island crater to lay a plaque, remembering the 22 people who died when the volcano erupted.
The group included relatives of some victims, at least one survivor, and a helicopter operator who rescued people on the day - but is also charged with health and safety breaches.
In photos of those on the island, no one is wearing hard hats or gas masks, and many are wearing jandals - including children.
But a spokesman says the group had a safety plan in place, and permission to go.
Sam Olley reports.
