Riverton/Aparima is in its cooler-water pattern: slower baits and the turn of the tide. Today brings cloud cover, wind ESE around 10 km/h, rising pressure near 1027 hPa and a high of 18 °C. Tides: high 12:11 pm, low 5:57 am and 6:23 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 11:06 PM-1:06 AM and 10:42 AM-12:42 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.
Drop to the bottom over reef and foul ground with cut bait, holding position over the rough patches.
Anchor or hold over the deeper reef edges with small baits close to the bottom, and move when a mark goes quiet.
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.
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: 11:06 PM-1:06 AM, 10:42 AM-12:42 PM, 5:30 AM-6:30 AM. Similar at 17 °C. The solunar majors shift about 50 minutes later.

The species that matter on Riverton/Aparima: 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.
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.
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.
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.
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.

Riverton/Aparima is a bay or coastal water in Southland, New Zealand, covered from the Southland reports and listed in all New Zealand waters.
Environment Southland’s Riverton Harbour guide forbids anchoring within 540 metres either side of the leads into Riverton/Aparima, except in an emergency or with the harbourmaster’s permission, and asks boats to pass under the Riverton Bridge only where signs show and in the direction marked. The 5-knot limit applies within 200 m of the shore, apart from a marked strip 10 m off the shore where craft moving anti-clockwise are exempt as long as they keep out of the way of commercial fishing boats entering or leaving.
Southland District Council’s 2025/26 annual plan sets aside NZ$814,000 to demolish and rebuild the Riverton T Wharf. For trip reports, Environment Southland’s guide points boaties to Bluff Fishermen’s radio on VHF channel 63.
Not within 540 m either side of the harbour leads, except in an emergency or with the harbourmaster’s permission.
