"The Business NZ family's involvement has been completely ethical at all times."
The training part funded by ACC had been run according to the brief and was achieving the outcomes it was set up for, he said.
Business NZ had now received "assurances from the minister that she had not meant to impugn the integrity of the Business NZ family".
CTU President Helen Kelly said criticism of the training by Ms Collins was "essentially an anti-CTU attack to cover her cuts to training".
Pointing to the string of recent forestry industry fatalities, Ms Kelly said: "Because the Government's under pressure for their appalling health and safety record she tries to shoot the messenger".
However, she said Ms Collins had spoken to CTU Secretary Peter Conway and while she wouldn't apologise "she said she will no longer use the word rort".
Ms Collins last night confirmed she had spoken with Mr Conway and had agreed to try "not to use those words".
However she maintained the scheme had been "a complete waste of money and a disgrace".
