There’s a belief the Government's new building directive for wool will be followed. 

From July, new builds worth more than $9 million and refurbishments costing over $100 thousand must use New Zealand wool where possible.  

The directive orders state agencies to follow the directive where practical. 

Wool Impact chief executive Andy Caughey told Mike Hosking it's not a rule, but strong advice. 

He says in two to three years time, people will see how obvious the solution was and regret not using wool earlier.
