A union representing wood processing workers says Government intervention is needed to save the industry from a crisis.
The Eurocell timber mill in Upper Hutt is the latest of several to announce it is closing, blaming difficulties such as getting affordable logs.
FIRST Union estimates that 1300 jobs have been lost.
It says the strong New Zealand dollar and delays in the Christchurch rebuild are not helping.
General secretary Robert Reid says a promise is needed that wood used in the rebuild will be New Zealand-made.
