Astrolabe Reef is near Motiti Island, off the Bay of Plenty coast in New Zealand. The reef, which breaks the water surface at low tide, is a renowned scuba diving spot that drops off to 37 metres (121 ft) in different parts. The reef was named by Jules Dumont d'Urville after his ship Astrolabe, when it nearly ran aground there on 16 February 1827.

Over 88 containers have fallen into the sea and some have washed ashore. Some of the containers that have fallen overboard contain dangerous chemicals.  The wreck broke in two during stormy weather on 7 January 2012.
