The election campaign tax battle turned nasty yesterday as Prime Minister John Key accused David Cunliffe of punishing grieving children with his capital gains tax and the Labour leader fired back an accusation that Mr Key had broken his promises to Pike River families.
Mr Key dialled up his attacks on Labour's capital gains tax plan after Mr Cunliffe on Wednesday said inherited homes would start being liable for the tax from one month after the death of the owner.
Mr Cunliffe yesterday backtracked from that, saying the period before the tax took effect would be worked out by an expert panel.
But with Mr Cunliffe already off-balance over whether family homes held in trust would be liable, Mr Key pounced.
He said Mr Cunliffe was telling New Zealanders "if they don't sell the family home of their deceased parents, then within one month they will have to start paying a capital gains tax".
