Given that Labour has been supportive of some environmental and worker protections in the past, we have to ask if these repeated outbursts from one of their senior MPs are simply the views of an individual, or something more.
The free rein given to Mr Jones to attack the Green Party on environmental issues suggests the latter. I hope this isn't the case. Protection of the environment is fundamental to what makes this a great place to live and is fundamental to our future economic prosperity.
The tourism industry - our second-biggest export earner - is built on the appeal of our natural environment. Our dairy industry, our biggest exporter, is dependent on our clean, green and safe brand - that's why exports into China are booming after their tainted milk scandal.
Just this month, the Pure Advantage group of leading New Zealand business people including Sir Stephen Tindall, Rob Fyfe, Jeremy Moon, Philip Mills, Sir George Fistonich and others released their second report on the green growth, green job opportunities for our economy. Their report offers many elements of an inspiring and lucrative alternative economic direction for our country.
Now that the failure of the National Government's economic policies is plain to see, it is refreshing to have a clear alternative strategy.
In this context, it is worrying that Mr Jones' anti-environmental tirades have been greeted with a deafening silence from the Labour Party leadership.
Mr Jones' outbursts won't deter the Green Party from doing our job in highlighting the risks of the National Government's decision to open up New Zealand to dangerous deep sea oil drilling.
The oil industry's promises of an economic boom are, in our view, inflated and need to be weighed against the real risks of a spill, highlighted by the Deepwater Horizon oil spill in the Gulf of Mexico that devastated local wildlife and cost more than $40 billion to clean up.
The oil and gas industry tends to be risk-rich and jobs-poor. Coal, oil, gas and metal mining employs only 3000 people, according to Statistics NZ. That compares with around 200,000 employed in manufacturing. Any future job growth in the mining sector won't compensate for the 40,000 manufacturing jobs lost in the past four years.
Mr Jones claims to be driven by a concern about jobs for Maori. Yet while he was chairman of Sealord, the company chartered a Ukrainian vessel and foreign workers were hired rather than New Zealanders. After Mr Jones departed, Sealord continued the practice of using foreign charter vessels instead of employing New Zealanders.
Mr Jones accepted $10,000 from the company for his last election campaign.
The mistreatment of crews working on foreign chartered vessels has been well documented; they are essentially slave labour. The National Government has taken far too long to start to address this and Mr Jones played a part in allowing this disgrace to happen in the first place.
National has failed to create jobs for the 175,000 unemployed New Zealanders. Labour and the Greens owe it to those workers, and those whose jobs are at risk, to work together to build a clean, green economy that delivers prosperity for everyone.
