Irritated and impatient customers have made a record-breaking postal season a nightmare for some PostShop workers, a union says.
This week, New Zealand Post delivered two million parcels -- 10 per cent more than last year.
Etu postal services organiser Joe Gallagher said it was a challenging time of year for everyone, but even harder for PostShop workers who frequently copped abuse from irritated customers.
He told Newstalk ZB working in a PostShop over Christmas was one of the hardest jobs on the planet, and people needed to be more understanding.
New Zealand Post service delivery chief Ashley Smout said the company processed more than 160,000 parcels overnight, 80 per cent more than a typical day.
