The Tasman Sea coast around Whanganui offers a range of coastal fishing opportunities — from land-based surfcasting at the city’s beaches to boat fishing further offshore for snapper, groper, terakihi, blue cod and squid. The west coast conditions can be challenging, but on good fishing days the region produces quality catches. Castlecliff and the North Mole at the river mouth are the main land-based spots, while the offshore grounds suit those who can get a boat out from the river mouth ramp.

Land-Based Coastal Fishing
Surfcasting is the most accessible form of coastal fishing around Whanganui, and the beaches and river mouth provide good options. The North Mole at the Whanganui River mouth is the standout spot — a rock wall at the northern side of the river entrance in Castlecliff, where snapper, kahawai and gurnard are regularly caught and notable fish including snapper approaching 9kg have been taken. Free parking is available beside the beach.
Castlecliff Beach and Kai Iwi Beach (14km north of the city) also offer surfcasting for the same species. Snapper are present across all of Whanganui’s beaches, along with sporting kahawai, gurnard and the occasional kingfish further out.
Offshore Boat Fishing
For those able to get a boat out, the offshore grounds beyond Whanganui offer a broader species range. Groper (hapuku) and bass are found in deeper water, while snapper, terakihi, blue cod and squid are available across a range of depths. The seafloor directly out from the Whanganui river mouth is predominantly sand and mud, with reef patches dotted around further offshore.
Launching from the Whanganui River mouth ramp is the practical option for local boat anglers. The ramp sits alongside a fixed-height boardwalk, making low-tide loading challenging, so preparing gear before launching is recommended. The channel from the ramp to the main river has been recently dredged. On fine days, it pays to get lines out early — the west coast is very exposed to westerly winds and swell, and conditions can deteriorate quickly.
