The National party's unveiled a tax plan worth $14.6 billion dollars over four years, that it says is targeted at the squeezed middle. National says a family with children and on the average household income of $120,000, would be up to $250 a fortnight better off. It will shift tax brackets and fund the income relief by cutting back office costs in government departments, reprioritisation and a new 15% foreign buyers tax on properties over two million dollars. National's finance spokesperson, Nicola Willis, speaks to Lisa Owen. [embed] https://players.brightcove.net/6093072280001/default_default/index.html?videoId=6336035064112
