Courier company DHL is in the middle of its busiest month ever, with one parcel being delivered every 1.6 seconds.
The company has been delivering an average of 37 parcels per minute throughout the month of December.
This compares to 24 parcels per minute in December 2015 and just seven parcels five years ago.
DHL Express NZ country manager Mark Foy says the surge in deliveries is the result of booming online shopping in the run up to Christmas.
"We'll do about 300 thousand shipments over December," says Mr Foy.
