Major active fault zones of New Zealand showing variation in displacement vector of Pacific plate relative to Australian plate along the boundary

The Marlborough fault system (also known as Marlborough tectonic domain[2]) is a set of four large dextral strike-slip faults and other related structures in the northern part of the South Island, New Zealand, which transfer displacement between the mainly transform plate boundary of the Alpine fault and the mainly destructive boundary of the Kermadec Trench, and together form the boundary between the Australian and Pacific plates.[3]
