A NZ Post investigation has revealed multiple items of mail have been tampered with, and in some cases taken, by a postal worker in Gisborne.
NZ Post service delivery regional manager Mario Kearney said an investigation was launched three weeks ago after a number of customer complaints were received.
"NZ Post takes delivering what people care about very seriously, so we are extremely disappointed to learn of this situation in Gisborne," Kearney said.
The number of items taken is still uncertain.
