The New Zealand Community Fault Model (NZ CFM) is a community-driven project led by GNS Science that pools the collective knowledge of the earth science community to develop a fault model for New Zealand which is open, updatable and publicly available. The NZ CFM v1.0 is a two- and three-dimensional representation of active and potentially active fault zones along the New Zealand plate boundary. Each fault zone in the model is associated with available kinematic information such as sense of slip, slip rake angle and slip rate, along with geometric parameters such as dip angle and depth of the fault plane. Geologists and geophysicists from several organisations collaborated to define the model, including uncertainties and limitations, to ensure it is fit-for-purpose for multiple applications. The New Zealand Community Fault Model and the associated data are of value to a range of kinematic, active fault and seismic hazard studies.

Active fault traces are a surface expression of permanent deformation that accommodates the motion within and between adjacent tectonic plates. We present an updated national-scale model for active faulting in New Zealand, summarise the present understanding of fault kinematics in 15 tectonic domains, and undertake some brief kinematic analysis including comparison of fault slip rates with GPS velocities. The model contains 635 simplified faults with tabulated parameters of their attitude (dip and dip-direction) and kinematics (sense of movement and rake of slip vector); net slip rate; and a quality code. Fault density and slip rates are, as expected, highest along the central plate boundary zone, but the model is undoubtedly incomplete, particularly in rapidly eroding mountainous areas and submarine areas with limited data. The active fault data presented are of value to a range of kinematic, active fault and seismic hazard studies.
