This report summarises the development of the 2021 New Zealand ground-motion database. Ground-motion intensity measures have been computed from strong-motion recordings for events with moment (and moment-equivalent) magnitudes equal to or greater than 4.0 from the year 2000 until the end of 2020. These measures include peak ground acceleration, peak ground velocity, cumulative absolute velocity, Arias intensity and pseudo-acceleration response spectra, among others. Along with these intensity measures, we have determined and/or collated earthquake rupture...
