New Zealand Post has stood down four courier workers in Wellington for not observing social distancing with each other on the job.
New Zealand Post central and southern general manager of operations Matthew Riordan said workers were aware of the need to maintain a two-metre separation with others at all times.
He said it was critical to enforce the rule, and four people in Wellington were stood down on Friday for breaching it.
They were stood down the same day RNZ aired a story with Wellington courier drivers who were concerned about working in unhygienic conditions through the lockdown.
Those courier workers complained that it was difficult to maintain social distancing when at times up to 100 people were working in the depot at the same time.
They said facilities had been shut off from the couriers, which meant that up to 100 staff members were sharing one kitchen and a few toilets - which were dirty.
Riordan said several changes had been made over the weekend to improve safety standards, and the stand-downs were not related to staff raising a red flag.
"We have put a number of improved protocols, information measures in place, to keep on top of the evolving situation.
"There is increased cleaning, we are sourcing all the critical supplies - we are working really hard to ensure the health and safety of our people does not get compromised."
Riordan said it was an unprecedented situation and things were rapidly changing, and they would be reviewing their health and safety protocols.
