The Lord Howe Rise is part of the continent known as Zealandia.

The Lord Howe Rise is an underwater plateau that extends from southwest of New Caledonia to the Challenger Plateau, west of New Zealand. To its west is the Tasman Basin and to the east is the New Caledonia Basin. Lord Howe Rise has a total area of about 1,500,000 square km, and generally lies about 1500 to 2500 metres under water. It is part of Zealandia, a much larger continent that is now mostly submerged, and so is composed of continental crust. It was rifted away from Eastern Australia by a mid-ocean ridge that was active from 80 to 60 million years ago, and now lies 800 kilometres offshore from mainland Australia.
