Today's Fishing Report

Tides: high 2:56 am and 3:24 pm, low 9:10 am and 9:39 pm: the moving water either side of each change is when this place feeds. Water sits around 12 °C for the season (estimated). With the waning crescent, the solunar majors run 10:22 AM-12:22 PM and 10:37 PM-12:37 AM: the windows to build the day around.
Sea perch
Good
Drop to the bottom over reef and foul ground with cut bait, holding position over the rough patches.
Kahawai
Good
Schools are harder to find, so go to them: river mouths and harbour channels at the turn of the tide, with a strip of fresh bait under a float or a soft bait retrieved slowly.
Tarakihi
Good
Anchor or hold over the deeper reef edges with small baits close to the bottom, and move when a mark goes quiet.
Red cod
Slow
Late autumn is the tail of the run and late spring its start; between them the schools are offshore.
Tie on: Two-hook ledger, fresh bait · Slow jig worked close to the bottom · Flasher rig, slow drift · Strip of kahawai or mullet. Prime windows: 10:22 AM-12:22 PM, 10:37 PM-12:37 AM, 5:07 AM-6:07 AM. Similar at 15 °C. The solunar majors shift about 50 minutes later.

Species guide
The species that matter on Sumner: seasons written for the southern year, and how to fish each one. Today's ratings live in the report above.
Blue cod
Year-round; spawning in late winter and spring
Rāwaru or pākirikiri in te reo Māori. A bottom fish found only in New Zealand, living near rough ground to 150 metres and more common south of Cook Strait. The Plenary rates it the most important recreational finfish in Marlborough, Canterbury, Otago and Southland. Blue cod can change sex from female to male, and males grow larger. The spawning season runs through late winter and spring: fish reef and gravel patches with cut bait on a large hook.
Sea perch
Year-round on reef and foul ground
Pōhuiakaroa in te reo Māori. The Plenary says sea perch are seldom targeted but widely caught, almost all on rod and reel from boats, and are now more often kept as an eating fish. The 2022–23 national survey placed most of the recreational harvest off the east coast of the South Island. The inshore species lives on or near the seafloor, mostly shallower than 250 metres. Drop to the bottom over reef and foul ground with cut bait, holding position over the rough patches.
Kahawai
Year-round on every coast; most fishing trips happen in summer
Kahawai (Arripis trutta) live right around New Zealand in coastal seas, harbours and estuaries, and run into the brackish lower reaches of rivers. A schooling fish that takes bait readily and eats mostly small fish and krill; MPI notes a second species, the Kermadec kahawai, which turns up seasonally around Northland. The Plenary records kahawai as an important customary food fish for Māori. Schools are harder to find, so go to them: river mouths and harbour channels at the turn of the tide, with a strip of fresh bait under a float or a soft bait retrieved slowly.
Red cod
About November to June on the Canterbury coast; the schools leave for deeper water over winter
Hoka in te reo Māori. A fast-growing, short-lived species. The Plenary says feeding schools arrive in the Canterbury Bight and around Banks Peninsula around November and are gone by about June, and that recruitment swings widely, so catches change a lot from year to year. The 2022–23 national survey estimated a recreational harvest of about a tenth of the 2017–18 figure. Late autumn is the tail of the run and late spring its start; between them the schools are offshore.
Tarakihi
Year-round on deeper reef; spawning in summer and autumn
Tarakihi are mostly taken on lines, often by people fishing for snapper or blue cod (Plenary). Juveniles grow up in shallow inshore nurseries such as Tasman Bay, the Kaikōura coast, northern Pegasus Bay, the Canterbury Bight and Otago, then move out to 50 to 200 metres at about 25 cm. The minimum fork length is 25 cm in every area. Anchor or hold over the deeper reef edges with small baits close to the bottom, and move when a mark goes quiet.
Flounder
Year-round in harbours and estuaries; young adults move offshore to spawn in winter and spring
Pātiki in te reo Māori. Four flounder species make up most of the recreational flatfish catch, taken in harbours, estuaries, coastal lakes and inlets around the country (Plenary). Most are netted or speared from the shore rather than caught on a line. Flatfish stay in water shallower than about 50 metres, and juveniles grow up on sheltered mud and sand flats. Fish the deeper harbour channels at low water and the flats as the tide comes back in.

Fishing Sumner: the full guide
Ramps at the estuary mouth
Christchurch City Council lists the Sumner Life Boat Ramp off Heberden Avenue in Scarborough as a free, all-tide, dual-access concrete ramp with a jetty and ample parking. Just inside the estuary, the Moncks Bay ramp off Main Road is also free and all-tide.
Rules around Sumner
Sumner falls under MPI’s South-East area rules and the coastal set-net ban to 4 nautical miles, and the estuary behind it is one of the places MPI excludes from the set-net exemption. To the south-east, the Lyttelton Harbour/Whakaraupō Extension Mātaitai Reserve comes ashore at Awaroa / Godley Head, and its Ngāti Wheke bylaws have applied since 1 October 2026.
Tide
LINZ’s Sumner Head secondary port is under 1 km from Sumner. Its mean high and low waters differ from Lyttelton by only a minute.
Common questions
Where do I launch a boat at Sumner?
At the Sumner Life Boat Ramp off Heberden Avenue, Scarborough, or the Moncks Bay ramp off Main Road. Christchurch City Council lists both as all-tide with no fee.
Do the Lyttelton mātaitai bylaws apply at Sumner?
The Gazette notice brings the extension mātaitai’s boundary ashore at Godley Head, which lies between Sumner and the harbour. The bylaws apply inside that boundary, so check MPI’s map before fishing near the head.
Which tide station is used for Sumner?
LINZ’s Sumner Head, a secondary port of Lyttelton less than 1 km away.
