At 1252hr a call was received from a 5m boat with 1 POB.  The boat was east of Whale Island and had a flat battery and needed assistance. Sea conditions were good with 9kt wind from NNW and a calm sea. At 1253hr a good samaritan offered to jump start the boat and at 1310hr the boat was started successfully and both boats were inbound to Whakatane. At 1327hr the boat was safely back in port. Many thanks to the good samaritan.
