Introduction

New Zealand is a mountainous island system of about 260,000 sq km area with much of the terrain at elevations in excess of 500 m above sea level. It is the emergent portion of two much larger crustal blocks, the Lord Howe Rise and the Chatham Rise-Campbell Plateau that are juxtaposed along the line of the Macquarie Ridge, the Alpine Fault and the Kermadec Ridge and Trough of the SW Pacific. The width of the continental shelf varies considerably from less than 5 km to the SW of South Island to more than 150 km to the west of Cook Strait. Water depths less than 500 m are widespread on the Chatham Rise and the Campbell Plateau, but most of the Lord Howe Rise is at depths greater than 1,000 m.
