Studies on self-reported behaviour are a poor substitute for assessing adherence to government recommendations. This study aimed to determine the percentage of pedestrians wearing masks in the Central Business District (CBD) and a suburb of Auckland, New Zealand (NZ). Methods: This direct observational study of pedestrians crossing two busy intersections occurred between 22 August 2020 and 7 March 2022. Data collection occurred at three separate times during the day, in the morning (from 8 to 9 am), noon (from 12 to 1 pm) and afternoon (from 4 to 5 pm) for precisely one hour each time. Results: Over 12 days of COVID alert level restrictions, we observed 30,855 pedestrians. Overall, 57.9% of pedestrians wore a mask outdoors. Masks-wearing was significantly higher in the CBD (64.0%) than in the suburb (38.7%), p < 0.001. Masks use was lower in the morning (51.1%) than at noon (56.1%) or afternoon (62.7%), p < 0.001, both in the CBD and the suburb. Conclusion: This was the first observational study in NZ examining the public’s mask use during the COVID-19 pandemic. From our observations, there may be opportunities for improvement in public face mask use rates to decrease the spread of COVID-19 in the population. In addition, our findings can inform national and international public health agencies about face mask uptake in public.Open Access This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.
