National is facing heat from another angle after the Council of Trade Unions launched a highly visible advertising campaign explaining - in its words - why the country will be worse off under a Christopher Luxon-led government.
The ads - on billboards and in newspapers - have been slammed by National as a nasty "American style" personal attack campaign and accused the CTU of being "intimately connected" with Labour.
That claim is denied by the Labour leader Chris Hipkins.
CTU president Richard Wagstaff spoke to Ingrid Hipkiss.
