5th June 2010, 4 men went out for a days fishing in a 5m Bayliner left for a days fishing around 10am. The sea was rough with a 2.5m swell although the day was fine. On arrival at the fishing reef the fishing was so poor they decided to return home and on the return journey the main engine failed. Their axillary engine was only 8hp and was unable to cope with the rough conditions. Unable to trigger the VHF repeater they managed to call a friend by cellphone who alerted Police. Coastguard Riverton volunteers were paged and they launched the Russel John Chisholm heading out to the GPS coordinates provided by the vessel in distress. Locating them at 11.30am they took them under tow and were able to return them safely to Colic Bay.
4th June 2010, Police called out Sumner Lifeboat to search for a person seen entering the water near Cave Rock by a member of the public at 16.59. Hamilton Jet Rescue was launched and a shoreline search was also carried out by Sumner Lifeboat volunteers. Apart from surfers no other person was located and the Police stood down the search at 18.26.
