Nicola Willis says the National's new proposed increase to the fuel tax, the new bed tax and the possible bank levy aren't new information.
A Taxpayers' Union Curia Issue poll shows 76 percent of National supporters want the party to promise no new taxes or tax increases.
The party yesterday outlined a promise for fiscal responsibility - including a commitment to lower the debt to GDP ratio and to get the books back into surplus.
Finance Minister Nicola Willis says these proposals have been documented and National's simply being straight with voters.
"Three issues we've already been very open and upfront about, and I can be very clear with you that there is nothing that we are considering that you haven't heard about."
