Lake Ngā Roto (Wairoto) is the largest of the Waipā peat lakes, about 19 km south of Hamilton and 8 km north-west of Te Awamutu. Fish & Game calls it a popular coarse fishery with good vehicle access and plenty of fishable water, and rudd, goldfish and catfish are abundant.
Check for algae before you go. The lake has had repeated cyanobacteria health warnings, and in the summer of 2021 to 2022 an algae die-off killed thousands of fish and closed the whole reserve. When a warning is in place, health officials advise against fishing.

About Lake Ngā Roto
Ngā Roto is a hypertrophic peat lake: rich in nutrients, cloudy, and shallow, with a maximum depth of about 4 metres and an average under 2.
Drainage has shrunk it from about 220 hectares to about 90 hectares of open water today, inside a recreation reserve of almost 175 hectares managed by Waipā District Council. The water is too murky for underwater plants to grow, and pest fish such as koi carp and catfish stir up the bottom.
The lake is a wāhi tapu. Mana whenua are Ngāti Apakura and Ngāti Hikairo, and the area was one of the first settled after Māori moved inland from Kāwhia.
Ngāti Apakura know the lake as Wairoto, and the council’s 2025 reserve management plan aims to confirm the traditional name. Several pā sites lie close to the lake, including the fenced Te Pūtere Pā inside the reserve.
The Battle of Hingakākā, in which about 7,000 Ngāti Toa warriors and allies fought about 1,600 Tainui, took place just south of the lake. The Tainui taonga Uenuku was buried near the lake for safekeeping at the time, and pou named Te Paenga o Uenuku now stand near where it was found.
More than 50,000 people visit the reserve each year, mostly to walk the loop track. The lake is also home to Ngā Roto Sailing Club and Te Awamutu Rowing Club, which hold regattas here, and game-bird hunters use it in season. The restoration of the lake and its margins won a Minister of Conservation wetlands award in 2000.
How to Fish Lake Ngā Roto
What to catch
- Rudd: the main target, and abundant. Rudd count as a sports fish in the Auckland/Waikato region, so you need a licence.
- Goldfish: abundant. No licence needed.
- Catfish (brown bullhead): abundant. No licence needed.
- Koi carp: present. Koi are a noxious fish: never keep or move one alive.
Methods and bait
Fish & Game’s general coarse fishing advice suits this lake. A float rig is the most common method, with the bait just on the bottom, or set at midwater for rudd.
Use a rod of 3 to 4 metres, line of 2 to 3 kg (heavier, 4 to 5 kg, if you are after koi) and hooks from size 8 to 12.
Good baits are bread crust or paste, worms, maggots and sweetcorn, and groundbait made from poultry meal and breadcrumbs helps hold fish in your swim. Lakes in this region are coarse fishing waters, where groundbait and more than one bait are allowed.
When to go
Summer is the season for coarse fish, which slow right down and rarely feed in winter. Unfortunately summer is also when algae blooms are most likely, so check the warnings first. Fish from the banks, and keep clear of club jetties and pontoons when rowers and sailors are using them.
Rules and Safety
Algae warnings
- The lake has had repeated cyanobacteria warnings, including from December 2024 to July 2025, October 2025 to February 2026, and again in February 2026.
- In the summer of 2021 to 2022 an algae die-off starved the water of oxygen, thousands of fish and eels died, and the whole reserve, including the walking track, was closed.
- When a warning is in place, health officials advise against all water activities, including fishing. The walking track usually stays open.
- Waikato Regional Council advises never taking or eating fish found dead, and gutting and rinsing any fish caught in affected water thoroughly in clean tap water. Do not eat kōura or shellfish from affected areas. Keep dogs away from the water.
- Check the LAWA swim site for Lake Ngāroto/Wairoto and Health NZ’s health alerts before every trip. If you feel unwell after contact, call Healthline on 0800 611 116.
