NZ Post has employed hundreds more staff to keep up with demand as it prepares for a sustained Omicron outbreak.
The pandemic has had a massive impact on online shopping over the last two years, and NZ Post has continued to increase capacity to meet the demand for parcel delivery.
NZ Post chief operating officer Brendon Main said: "We brought on 800 extra people at the end of last year to deliver over 50 million parcels in the last six months of the year. It was the biggest Christmas in history for NZ Post and we worked really hard to scale up and deliver for Kiwis."
Main said a sustained Omicron outbreak will mean different challenges for NZ Post.
"We're preparing for both an increase in demand for parcel delivery, as well as a decrease in resource, as it's likely that at any given time some of our workforces will be unwell or self-isolating," he said.
