Political parties should be in the practice of jettisoning policies that serve only to hamper their electoral prospects. It is up to any new leader to recognise these and act. On that basis, the Labour Party's David Cunliffe has done well to dump two tax policies of one of his predecessors, Phil Goff - the removal of GST from fresh fruit and vegetables and the setting of a tax-free band on income below $5000. Both were poorly directed, and the fruit and vegetable initiative, in particular, could have had an array of unhelpful consequences.
This was recognised by Mr Cunliffe's immediate predecessor, David Shearer. In his first major speech as leader almost two years ago, he indicated the policies would be dropped. In making that dumping formal, Mr Cunliffe suggested that new evidence showed fresh fruit and vegetables were eaten mainly by those who could afford more, and said the party must seek a more targeted way of providing relief for the poor.
Yet sufficient evidence to rule out the policy was available even as Mr Goff was establishing it. As much as it might be assumed that a price reduction would trigger a change in consumer buying, researchers at Auckland and Otago universities found that discounting GST prompted only a "modest" improvement in healthier purchases. The impact on overall diet was, therefore, very limited. It was certainly not sufficient to warrant tampering with an important aspect of this country's goods and services tax.
This was recognised by Helen Clark during the final period of her prime ministership. When pressed to drop the GST on food, she pointed to the advantages of a system that applied across the board and was, therefore, generally regarded as simple to administer. "That means it is very low on complexity, which means it is low on compliance costs, so, therefore, there would be considerable reservation about changing it," she said.
Britain's experience has confirmed the perils of creating exemptions. There, most food does not attract value-added tax through a complex schedule that aims to separate essentials from luxury items. The outcome has been confusion, and a situation that benefits lawyers more than anyone else.
