Pre-departure testing seems to have had little impact on the number of Covid-19 cases being detected at the border, a Stuff analysis shows. But has it made a difference to the number of people testing positive in managed isolation, upon arrival in New Zealand? Even this negligible drop (which is statistically insignificant) may have little to do with pre-departure testing. Abigail Dougherty/Stuff Shaun Hendy says modelling he and other researchers did show pre-departure testing would have a limited effect. He still believes pre-departure testing is “useful and justifiable” but agrees there’s a lot of uncertainty built into the policy.
