Short summary

Despite the importance of marine aerosol measurements for constraining climate models, these measurements are scarce. We measured the aerosol particle number size distribution in coastal New Zealand over a total period of 10 months. This paper analyses the aerosol properties at the site, with a special focus on new particle formation and marine air masses. New particle formation was observed frequently, but in marine air masses it did not follow traditional event criteria.
