Posties are in an uproar and mail will not be delivered in central Christchurch today after heavy dust, which workers fear could be asbestos, closed the city's mail hub.
Construction workers transforming the Hereford Street New Zealand Post building for the new city council headquarters turned up heavy dust yesterday.
This morning, posties on the fourth floor of the building were sent home because of fears for their health.
Engineers Printers and Manufacturers Union national postal and logistics organiser Anna Kenny said workers had been stood down for 24 hours pending a check of air quality.
The building was checked for asbestos in November and none was found, he said.
"Having said that, however, given that the dust is particularly unpleasant and unsafe and of an unknown source, we've asked for further air quality checks to be done before people go back in to that environment and we also want the hazard eliminated," Kenny said.
A New Zealand Post employee working on the ground floor said the building was cleared.
"We've had to have the building evacuated - all the posties are all up in arms. And the (workers on the) private boxes and the post shop have all been sent home for the day now," the man, who did not want to be named, said.
Kenny said he understood there would be a reassessment of mail delivery tomorrow morning at 7am. "But it's still subject, in our view, to confirmation that the air quality is safe."
New Zealand Post is yet to reply to a request for comment.
The Christchurch Mail Centre in Christchurch, New Zealand, was evacuated Friday after employees refused to continue working due to exposure to heavy amounts of dust suspected to be asbestos. Tuam 2 Ltd, the company set to convert the 27-year-old Christchurch Mail Centre into a new city council building, has been aware of the presence of asbestos in the building since May 2008. Hawkins Construction contacted the New Zealand Department of Labour, voicing concerns of possible exposure to asbestos material. Testing is currently underway at the facility to determine the nature of the exposure.

The Christchurch Mail Centre is operated by New Zealand Post. According to Christchurch Delivery Business Leader Duncan Burman, approximately 50 post workers operate out of the facility, which services about 35,000 addresses in the central Christchurch region.

blue asbestos'', a type of asbestos found in Africa and Australia According to a paper released in June by the Environment Canterbury on the subject of asbestos removal: "Exposure can occur when materials containing asbestos are sanded, sawn, drilled or handled in maintenance or removal tasks." Exposure to asbestos fibers can lead to the diseases mesothelioma, lung cancer, chest cancer, and asbestosis. 

Tony Marryatt, chief executive of the city council, was asked by Councillor Helen Broughton for an explanation of the incident. Councillor Broughton is the only councillor who voted against construction of new city council buildings. 

"Councillors made an assumption that the building had been checked by a professional and that's the question I'm going to ask the CEO now. I've asked him for a report on it and I want to see the professional opinion from a building consultant who said that the building was sound and able to be refitted and didn't have any major problems," said Broughton in a statement in ''The Press''.


The owners of the Christchurch Mail Centre informed New Zealand Post that testing performed in November confirmed there was no asbestos "in the area". 


Anna Kenny, a spokesperson for the New Zealand trade union Engineering, Printing and Manufacturing Union said concerns were raised about plumes of dust Friday morning suspected to be asbestos, but that there has been no confirmation of this yet. 

According to ''The Press'', Kenny also confirmed that no asbestos was found in a check of the building in November. "Having said that, however, given that the dust is particularly unpleasant and unsafe and of an unknown source, we've asked for further air quality checks to be done before people go back in to that environment and we also want the hazard eliminated," stated Kenny.
