HAMILTON, New Zealand: An investigation was underway in New Zealand Sunday to determine why a chartered fishing boat capsized, claiming at least seven lives in stormy seas that kept other vessels inshore.The victims were identified as a group of Pacific Island friends who regularly fished together, and the captain of the vessel. “Investigators are working to establish exactly what happened,” police Inspector Mark Fergus told reporters. There were 11 people on the boat, The Francie, when it sank at the entrance to Kaipara Harbor, north of Auckland, on Saturday afternoon. Three survivors were rescued and seven bodies recovered, police said. Aerial and shoreline searches continued for the missing man, who is presumed dead.
