It's 30 years since Greenpeace ship, the Rainbow Warrior, was sunk by French Secret Service agents in Auckland's Waitemata Harbour.
The ship now lies on an artificial reef in Matauri Bay, Northland and has become one of the country's premier dive sites.
So what is this piece of New Zealand history really like now and how popular is the wreck 30 years on?
Dive instructor Sam Jupe joined Paul Henry this morning and says it is an amazing dive spot.
"It is rated one of the top 10 dives in the world. It's super colourful and the best thing is the depth. It is accessible to everyone. It's about 27 metres to descend but the main deck is 17 metres so it's within easy recreational limits."
