During the Alert 4 lock down we encourage you to do all of your banking, including making tax payments, at home online. If you do need to make a payment or do other essential banking at a branch, selected Westpac branches will be open for strictly limited hours on Wednesdays only. Access to the branches will be controlled to enforce appropriate social distancing. For a list of which branches will be open from 10:00am – 1:00pm on Wednesdays, visit https://www.westpac.co.nz/who-we-are/covid-19/branches-and-atms/.
The IRD details the other (preferred) options for making payments on their website.
