Te Moana-o-Raukawa, or Cook Strait, is a significant and dynamic body of water separating New Zealand's North and South Islands. It connects the Tasman Sea to the west with the South Pacific Ocean to the east, creating a powerful and often turbulent marine corridor. The strait is steeped in Māori history and legend, notably as the site where the navigator Kupe is have defeated the giant octopus, Te Wheke. Its waters are known for strong tidal currents and complex underwater topography, including the submerged river valleys that form the intricate Marlborough Sounds at its northern reaches. The Wellington region on the northern shore and the Marlborough Sounds on the southern side provide the primary access points for anglers targeting a variety of robust saltwater species.
