Earlier this month a group of ang;ers searching for white bait located a little-known but very important shipwreck from World War II. Channel33 news reports, U-3523 was a type XXI U-boat, the Third Reich’s most advanced long-range submarine. Some researchers have speculated that the wreck could have been used to transport valuables and even high-ranking Nazis to New Zealand in the waning days of the war. U-3523 was designed to run quietly to avoid detection and, most importantly, it may have been capable of crossing the Lake.
