National has denied it misled voters before last year's election, when it vowed not to introduce any new taxes, by announcing two new taxes in this week's Budget.
The Government has consistently denied its changes to taxing the capital gains on property and the introduction of a new airport levy are new taxes, with Finance Minister Bill English today accusing anyone calling them a tax of playing "word games".
It came as Mr English denied National had misled voters.
"No, we didn't. The airport levy is a user charge, and across Government we have user charges for all sorts of things," he told TV3's The Nation.
"In this case we've got demand at the border, lots more people coming in, it's a problem with success, we've got biosecurity risks, and so we've taken the opportunity to shift the cost from the tax payer to the user."
