National Deputy Leader Nicola Willis has been positioned as the party's key political attack weapon against Winston Peters as the coalition faces mounting electoral pressure.

As Finance Minister, Willis will need to address voter concerns about increasing household expenses while simultaneously maintaining her aggressive political positioning against coalition partners. The piece indicates that economic pressures on households are becoming a central electoral battleground that could determine the government's fate.
