Regulation changes aimed at improving trout quality and increasing fishing opportunities will come into force before the Taupō fishing season opening on July 1.

The most notable change is an increase to the daily bag limit, rising from six to eight trout, as part of efforts to better manage fish numbers and sustain a healthy balance with their primary food source, smelt.

Department of Conservation Taupō operations manager Dave Conley said in a media release that the region’s spawning streams are “hyper-productive”, with high numbers of juvenile fish entering the fishery each year.

“This means harvest is an essential tool to keep numbers in check and maintain a healthy trout population,” Conley said.

He said regulation changes are guided by a comprehensive monitoring programme, alongside feedback from anglers.

“We also listen carefully to the angling community, and a number of changes this year reflect this.”

A key update will affect Lake Ōtamangakau, where the traditional February closure will be replaced by a more flexible approach. Closures will now be determined based on weather conditions, particularly heat risks that can impact trout health.

Other changes include simplifying regulations to make them easier for anglers to understand, with updates to rules around soft baits.

Fishing access will also be expanded, with fly-only restrictions relaxed at the Otaketake and Waitetoko stream mouths to encourage greater use of those areas.

The Department of Conservation manages the Taupō Fishing District as a wild trout fishery, attracting thousands of anglers annually.

Conley said the regulations are designed to protect the long-term future of the fishery, supported by Fishery Rangers monitoring activity across rivers and lakes.

“To support the regulations we have Fishery Rangers out ensuring everyone follows the rules – helping to protect the fishery we love,” he said.

Licence fees will remain unchanged for the 2026/27 season, with the department aiming to keep fishing affordable and accessible.

New season licences go on sale from June 24, before the opening day on July 1.
