The Employment and Safety Minister expects the health and safety bill delayed by resistance within the National Party caucus to be reported back to Parliament by the end of the week, as expected.
The bill passed its first reading in Parliament but was stuck in select committee for two months because National MPs failed to agree on how far the changes should go.
There were concerns about the effect the new law would have on small business, the voluntary sector and on farmers in particular.
Minister Michael Woodhouse said he was confident the bill was now in good shape.
"This is the biggest reform in health and safety legislation in 25 years, clearly there's going to be quite a bit of scrutiny on it and a few changes as there always is on bills in select committees, so the matters are minor and technical, with one exception we've raised the issue of cause of death as a specific offence in the bill and I'll be making some decisions about that with caucus this week."
Mr Woodhouse said he had not bowed to any sector interests by making several changes to the original bill.
