The Taupo fishery is a unique system for the New Zealand and requires a seperate fishing licence.

The country's largest lake supports and replenishes each river and stream with fish almost on a daily account. Unlike nearly every other water in New Zealand, where to fish within sight of other anglers is uncommon, some days with Turangi certainly requires an amount of courtesy and etiquette to fish in harmony. If you strike a day where the fish are running, take along extra flies and tackle. Be ready for near bust offs, burning runs as lake fed beasts try and melt your reel. Prepare your gear by visiting the many tackle shops for the best flies and techniques. But what they can't fix are your aching arms from casting and tired jaw from smiling. However a meal and a few cold drinks afterwards at the local Turangi Tavern certainly help ease the aches and pains.
