David Bishop, of Kerikeri, and his mate Bryce Taylor, of Glinks Gully, had been fishing at the entrance of Kaipara Harbour on Saturday when they decided to call it a day around 5pm.
Their route home took them around Pouto Point, past the historic lighthouse, and north up Ripiro Beach towards Dargaville.
A few hundred metres north of the lighthouse they saw something that had them rubbing their eyes in disbelief.
"When we were fishing we heard a bit of thunder, but no rain or anything, so sweet as, we finished fishing and come around the corner past the lighthouse, and then it was like, 'Holy s***!' We just couldn't believe it."
