The Mohaka is one of north island New Zealands premier back-country trout streams. Here, we load a large helicopter with a white water raft, provisions and a guide and fly into the absolute headwaters of the river. When we get there its ready the fly rods, inflate the raft and set off on a five day odyssey down-stream, sight casting to trophy sized trout beneath towering gorges and ferns. Campfires beside the river bed amongst incredible scenery end each days adventure.
