The Melling station building at the end of a Hutt Valley commuter train line has been closed after testing positive for asbestos.
Wellington Regional Council said on Wednesday tests revealed the presence of asbestos dust but not airborne asbestos and there is no risk of people inhaling it.
However, it said the building needs to be cleaned and will remain closed until that is complete and tests show it is safe to reopen.
Tickets for single trips can be bought on trains servicing the Melling line and 10-trip tickets and monthly passes at Wellington station.
The dust was revealed as a result of a council testing programme on all stations.
The council says non-public areas at three other stations have been sealed off and will be cleaned thoroughly. At Taita station, also on the Hutt Valley line, asbestos has been found in the signal box.
This is now closed until it's been cleaned and the council warns there is likely to be some delays to services.
