Times and heights follow LINZ's method for secondary ports (the standard port's prediction plus the published mean differences and range ratio); checked against LINZ's own daily prediction for Raglan over a week on 7 October 2026, the method came within 13 minutes and 0.2 m. Heights are above chart datum. These are LINZ predictions, not the official tide tables for navigation, and wind and air pressure can move the real tide by tens of minutes.
Wairau Bar is in its cooler-water pattern: slower baits and the turn of the tide. Today brings cloud cover, wind SE around 14 km/h, rising pressure near 1028 hPa and a high of 15 °C. Tides: high 5:14 am and 5:40 pm, low 11:26 am and 11:50 pm: the moving water either side of each change is when this place feeds. Water sits around 13 °C for the season (estimated). With the waning crescent, the solunar majors run 11:26 PM-1:26 AM and 11:02 AM-1:02 PM: the windows to build the day around.
The spawning season runs through late winter and spring: fish reef and gravel patches with cut bait on a large hook.
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.
Anchor or hold over the deeper reef edges with small baits close to the bottom, and move when a mark goes quiet.
Fish slower as the water cools: an anchored ledger rig in harbour channels or on the sand off the beaches, with fresh bait.
In spring the schools bunch up before moving onto their spawning grounds; in autumn and winter they spread into deeper, more open water. Either way, fish the 15 to 60 metre marks with baits on the bottom and time the session around the tide change.
Drop to the bottom over reef and foul ground with cut bait, holding position over the rough patches.
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: 11:26 PM-1:26 AM, 11:02 AM-1:02 PM, 5:22 AM-6:22 AM. Warmer at 18 °C with likely rain: fish ahead of the front. The solunar majors shift about 50 minutes later.

The species that matter on Wairau Bar: seasons written for the southern year, and how to fish each one. Today's ratings live in the report above.
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.
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.
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.
Kumukumu in te reo Māori. Red gurnard live across harbours and shallow coastal waters, which the Plenary says makes them an important recreational species, often caught by people fishing for snapper and tarakihi. They spawn through spring and summer, and small juveniles shelter in shallow harbours. Fish slower as the water cools: an anchored ledger rig in harbour channels or on the sand off the beaches, with fresh bait.
Tāmure or kouarea in te reo Māori. MPI describes snapper as the dominant fish of northern inshore waters, most common where the sea is warmer and especially in the Hauraki Gulf, at home on reef as well as sand and mud, usually between 15 and 60 metres. The Fisheries Assessment Plenary calls it the largest recreational fishery in New Zealand. In spring the schools bunch up before moving onto their spawning grounds; in autumn and winter they spread into deeper, more open water. Either way, fish the 15 to 60 metre marks with baits on the bottom and time the session around the tide change.
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.
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.
You do not need a licence to fish in the sea around New Zealand, but the Ministry for Primary Industries (MPI) sets daily limits, minimum sizes and closures for each area, and Wairau Bar is in the Challenger area. The figures below are per person per day, as MPI's area page printed them on 7 October 2026. Fishing in rivers and lakes needs a licence: New Zealand fishing licence.

Wairau Bar is a bay or coastal water in Marlborough, New Zealand, covered from the Marlborough reports and listed in all New Zealand waters.
DOC’s Wairau Lagoons Walkway starts at the end of Hardings Road, which leaves State Highway 1 about 5 km south of Blenheim, and follows the lagoon shore to the main channel. DOC explains that the lagoons built up over some 6,500 years behind an 8 km boulder bank, and that the tide flushes in and out of them every day. In the channel lies the hulk of the Waverley, towed to the Wairau River mouth to be sunk as a breakwater but swept upstream by a flood first.
MPI bans set netting out to 4 nautical miles from Cape Jackson to the Clarence River, and names Te Koko-o-Kupe / Cloudy Bay, Clifford Bay and Cape Campbell in that rule. Its Challenger map draws the band without a break down the east Marlborough coast.
LINZ calculates the Wairau River Entrance from Wellington, with high water about 1 hour 10 minutes after Wellington on average and the same range ratio.
MPI prohibits set netting within 4 nautical miles of shore from Cape Jackson to the Clarence River, a stretch that includes Cloudy Bay, Clifford Bay and Cape Campbell.
