On Wednesday, 5 October 2011, the container ship MV Renaran aground on the reef. By Sunday, 9 October, a 5-kilometre (3.1 mi) oil-slick threatened wildlife and the area's rich fishing waters. By 13 October the ship had started to list and rock in the waves. Over 88 containers, some containing dangerous chemicals, fell into the sea and some washed ashore.[3] The wreck broke in two during stormy weather on 7 January 2012.
An exclusion zone was placed around the wreck during salvage and recovery operations, and this lasted until April 2016, when the reef was re-opened to vessels under 500 tonnes (550 short tons). The reef and the unsalvaged remains of the Rena have now become a popular dive site.[4][5]
