Labour leader Andrew Little has come out swinging against workplace health and safety regulations proposed by the government.
On TV3's The Nation this morning, Mr Little denied playing politics with workers' health and safety by opposing the law change making its way through parliament.
The proposals have this week attracted ridicule by including worm farming and mini-golf in a high-risk category, which excludes dairy farming and other occupations perceived as risky.
"The main thing about the Health and Safety Reform Bill was about getting things in place to have a good culture in the workplace. There was a consensus about that and when the bill was introduced it was actually in pretty god nick," Mr Little said.
"Something has changed in the last few months. I think what's happened is that the National Party has decided, or their supporters in the farming lobbies have said we don't want a bar of this and even though that is the sector that has the worst record of fatalities and serious accidents, this government is bending over backwards to exclude farming businesses that actually need legislation like this to improve their performance."
