Panel to decide if lagoon should be opened

A Southland lagoon will be the subject of a hearing to decide if periodic openings to the sea should be allowed.
Waituna Lagoon is located southeast of Invercargill next to Toetoes Bay, and forms part of an internationally significant wetland.
But the area has been troubled with both high water levels and algae outbreaks in recent years due to nutrient buildup, with runoff from surrounding farmland proving an issue.
A previous resource consent for opening the lagoon expired in 2022, meaning two openings in 2024 were completed under emergency powers.
Last July, Environment Southland received a resource consent application from itself, Te Rūnanga o Awarua and the Department of Conservation to periodically open the lagoon to the sea.
The goal was to create a regime for managing the lagoon's water levels, a report said.
A total of 51 submissions were received during a public notification period, of which 42 opposed the application and wanted to be heard at a hearing.
On Thursday, Environment Southland appointed three people to an independent panel to decide the application's fate — accredited hearing commissioners Mark St. Clair, Megan McKay and Dr Ian Boothroyd.
Council chairman Nicol Horrell said staff had worked hard to get commissioners in place.
"I think that'll be appreciated by some of the submitters, so well done."
The hearing will be held at Environment Southland from July 29-31. The council has already sent the dates to relevant parties.
Submitters in favour of the consent include Southland Conservation Board, Te Ao Mārama Inc and Te Rūnanga o Ngāi Tahu.
Federated Farmers opposed it based on proposed water levels for opening, while Forest & Bird was mostly supportive but also took issue with some of the proposed levels.
Waituna Lagoon is home to native birds, fish and plants.
In 1976, the area became the first in New Zealand to be recognised under the Ramsar Convention as a wetland of international significance.
