About Hurunui River

The Hurunui drains the eastern side of the Southern Alps about 130 km north of Christchurch. Its North Branch flows through Lake Sumner and joins the South Branch southeast of the lake, and the river then runs east through a string of short gorges, the Balmoral Forest and hill country to the sea south of Cheviot. It has some of the most productive trout water in New Zealand. Fish & Game's guide says the 10 km from Lake Sumner to above Maori Gorge holds more than 50 large brown trout a kilometre, up to 3.5 kg, all year round. The lower river and the mouth are known for sea-run salmon.

Below Lake Sumner the North Branch is large and clear, and it stays clear after a fresh. It flows over rock and gravel with deep pools and big runs, and it is dangerous to cross and tricky to wade. Long casts, mostly blind, are the rule, and blind fishing the big pocket water is very effective. Fish stonefly nymphs or small tungsten beadheads such as a gold bead Hare and Copper, or a well-hackled attractor dry such as a Stimulator, upstream on a floating line. Stand well back and spot fish before you cast. When the river is coloured, spin a Tasmanian Devil or a Toby into the calm water at the top of pools. Above Lake Sumner and in the South Branch there are fewer fish, and Fish & Game asks anglers to release them where they can. The prevailing nor'wester blows downstream.

The salmon season in the lower river runs from mid January to mid March. Salmon run as soon as the river clears after a fresh. Look for deep, slow water and places where the river meets rocky outcrops or bluffs, and fish a 10 to 22 g Zed spinner right on the bottom. At the mouth, fish the surf when the river is low and salmon are waiting outside, or the gut on the top half of the incoming tide after a fresh. A run of sea-run browns in December can give good sport. Environment Canterbury runs the two gauges on this page, and it sends readings only up to the previous midnight, so the newest value can be up to a day old. Didymo is present, so clean your gear, waders and boots before you move between rivers.

Sections

5 reaches

North Branch above Lake Sumner

WadeBrown Trout

The North Branch headwaters above Lake Sumner: a moderate-sized, clear, shingly river that floods easily. On a bright day you can spot and stalk the brown trout, but they spook easily and hide for a day once disturbed. It can be waded and crossed safely at normal flows. A designated water above a point 500 m upstream of the lake, and a controlled fishery above the swing bridge where the 4WD track ends. A strong nor'wester often blows down the valley.

Best for: Sight fishing for good-sized brown trout, for fit anglers with a full day to spend.

Lake Sumner to the South Branch

WadeBrown Trout · Rainbow Trout

Below Lake Sumner the North Branch is large and clear, and it stays clear after a fresh. Fish & Game's guide calls the 10 km from the lake to above Maori Gorge, where the road first comes near the river, one of the most productive trout reaches in New Zealand, with more than 50 large fish a kilometre. Deep pools and big pocket water over rock and gravel. It is hard to cross and tricky to wade, and long casts, mostly blind, are the rule. Foot access only from the Sisters Stream footbridge up to the lake. Open all year for trout, fly and spinner.

Best for: Brown trout to 3.5 kg, blind fished in the big pocket water with stonefly nymphs and tungsten beadheads.

South Branch

WadeBrown Trout · Rainbow Trout

Smaller and less stable than the North Branch, and it colours after rain. Good fishing above the confluence, but access through and above its gorges is hard. The trout get wary under angling pressure, so fish it early in the season, and Fish & Game asks you to release them. A designated water above the North Esk confluence. Foot access from the confluence, and all other access through Esk Head Station with the landowner's permission. The South Branch gauge reads this water.

Best for: A few good-sized brown trout in the upper water, early in the season, catch and release.

South Branch confluence to the Mandamus

WadeBrown Trout · Rainbow Trout

Below the branches the river runs through a series of short gorges. You can catch trout anywhere down to the gorge above the Mandamus confluence, which is almost unfishable because of its steep banks. Lake Sumner Road follows part of this reach, and you can walk down to the river at Surveyors Stream, where the road leaves it.

Best for: Brown trout in the deep pools and runs, on nymphs when the river is low and clear and spinners when it is coloured.

Mandamus to the sea

WadeSalmon · Brown Trout

The large, shingly, braided lower river through the Balmoral Forest and hill country to the sea south of Cheviot. It can be dirty and suits spinning for salmon from mid January to mid March, best as the river clears after a fresh. Brown trout hold in the deep holes and gorges all year, early in the season under the willows, and a run of sea-run browns in December can give good sport. The State Highway 7 bridge at Hurunui gives access to both banks, and roads off State Highway 1 reach the lower river and the mouth.

Best for: Quinnat salmon on 10 to 22 g Zed spinners fished on the bottom, and brown trout and sea-run browns.

Best seasons

All year for trout below Lake Sumner, and October to April in the branches. Early season is best in the South Branch, before the fish wise up. Salmon run from mid January to mid March, and sea-run browns in December. Fish & Game says the river generally becomes fishable once it drops below about 35 m³/s (1,240 cfs), and trout anglers in the upper river like it at 25 m³/s (880 cfs) or less, for better access along the banks. The guide does not name its gauge. The SH1 gauge on this page reads the whole river, so it runs a little higher than the upper river. About 10 m³/s (350 cfs) is close to its summer low. Its newest reading is from the previous midnight. Trout feed best at about 10 to 18 °C (50 to 64 °F).

Regulations

Between the Lake Sumner outlet and the South Branch confluence, trout are open all year, fly and spinner, bag 2. Below the South Branch, trout are open all year to fly, spinner and bait, bag 2, and salmon from 1 October to 30 April under the sea-run salmon rules. The North and South branches are open 1 October to 30 April, fly and spinner, bag 1, with designated waters in their upper reaches.

Licence: A Fish & Game New Zealand sports fishing licence. The upper North and South branches also need a designated waters licence, and the North Branch above the swing bridge a controlled-period licence during its controlled period. Salmon fishing needs a Sea-run Salmon Licence and a season bag limit card.

North Branch and its tributaries upstream of a point 500 m above Lake Sumner (signposted): designated water, open 1 October to 30 April, fly and spinner, daily bag 1 trout, maximum length 400 mm.
North Branch upstream of the swing bridge: also a controlled fishery, so you need a controlled-period licence during its controlled period.
North Branch below the designated water, down to Lake Sumner: open 1 October to 30 April, fly and spinner, daily bag 1 trout, maximum length 400 mm.
South Branch upstream of the North Esk confluence: designated water, open 1 October to 30 April, fly and spinner, daily bag 1 trout, maximum length 400 mm. Below the North Esk: the same, without the designated water licence.
Hurunui River between the Lake Sumner outlet and the South Branch confluence: trout open all year, fly and spinner, daily bag 2.
Hurunui River below the South Branch confluence: trout open all year, fly, spinner and bait, daily bag 2. Salmon open 1 October to 30 April, fly and spinner, under the sea-run salmon rules: a Sea-run Salmon Licence, a season bag limit card, and 1 sea-run salmon a season across the North Canterbury and Central South Island regions combined.
North Canterbury region: no more than 4 sports fish a day, no trout or salmon under 300 mm, and no salmon fishing in any river from 1 May to 30 September. No taking salmon from a river between 11 pm and 4 am in December and January, or between 10 pm and 5 am in other months.
Felt-soled waders and boots are banned in New Zealand.

Lake Sumner itself is open all year, fly and spinner, bag 2, and no chinook salmon taken from it may be kept. Check North Canterbury Fish & Game's website (https://fishandgame.org.nz/north-canterbury/) for the controlled period dates and the current rules before you go.

Getting there

Culverden, Canterbury

About 1 hr 15 min (84 km) from Christchurch to the State Highway 7 bridge at Hurunui, and about 2 hr (129 km) to the upper river on Lake Sumner Road.

Camping: Accommodation at Culverden, Hanmer Springs and Cheviot.

Lake Sumner Road skirts the upper river. From the Sisters Stream footbridge to Lake Sumner, access is on foot only. A 4WD track off Lake Sumner Road reaches the North Branch above the lake and ends at a swing bridge, and you need the combination for a gate past Loch Katrine from DOC's Christchurch office. The South Branch is reached on foot from the confluence, or through Esk Head Station with the landowner's permission. On the lower river, the State Highway 7 bridge at Hurunui gives access to both banks, and side roads off State Highway 1 reach the lower river and the mouth.
