Abstract. This paper presents the current state-of-knowledge of the New Zealand (Aotearoa) last interglacial (MIS 5 sensu lato) sea-level record compiled within the framework of the World Atlas of Last Interglacial Shorelines (WALIS) database. Seventy-seven total relative sea-level (RSL) indicators (direct, marine-, and terrestrial-limiting points), commonly in association with marine terraces, were identified from over 120 studies reviewed. Extensive coastal deformation around New Zealand has resulted in a significant range of elevation measurements on both the North Island (276.8 to −94.2 msl) and South Island (173.1 to −70.0 msl) and prompted the use of RSL indicators to estimate rates of vertical land movement; however, indicators lack adequate description and age constraint. Identified RSL indicators are correlated with MIS 5, MIS 5e, MIS 5c, and MIS 5a and indicate the potential for the New Zealand sea-level record to inform sea-level fluctuation and climatic change within MIS 5 (sensu lato). The Northland (North Island) and Otago (South Island) regions, historically considered stable, have the potential to provide a regional sea-level curve in a remote location of the South Pacific across broad degrees of latitude. Future work requires modern analogue information, heights above a defined sea-level datum, better stratigraphic descriptions, and use of improved geochronological methods. The database presented in this study is available open-access at this link: http://doi.org/10.5281/zenodo.4056376 (Ryan et al., 2020a).

A trench across the Ohariu Fault at MacKays Crossing revealed evidence and provided radiocarbon age constraints for three surface-rupture events in the last 5300 cal. yr BP. The two older events are dated for the first time at 5270-4410 and 4810-3260 cal. yr BP. The youngest event is correlated to the most recent event, dated elsewhere along the Ohariu Fault, at 1050-1000 cal. yr BP. Using statistical methods incorporating inter-event times, mean slip rate, and single-event displacement, and their uncertainties, a best estimate mean recurrence interval of 2200 yr is calculated for the Ohariu Fault, with minimum and maximum 68% and 95% confidence interval limits of 1300 and 3800 yr, and 800 and 7000 yr, respectively. Following the procedures outlined in the Ministry for the Environment Guidelines, these data place the Ohariu Fault in Fault-avoidance Recurrence Interval Class II (>2000 to 3500 yr), with medium to low confidence of classification.
