In March 2022, Aotearoa New Zealand re-opened its border allowing quarantine-free travel for many travellers. Here, the authors describe circulating Omicron sub-variants before and after the reopening of the border and show that the rate of viral introductions grew roughly linearly with the increase in daily international travel.
