KEY POINTS:
With less than two weeks before polling day National is screening new ads challenging Labour's record while a billboard erected in Tauranga pokes fun at New Zealand First leader Winston Peters.
National's television advertisements question Labour's record over the past nine years.
The ads feature negative newspaper headlines on education, health and law and order, and a female voice over asks the question: "Do you really expect anything to change if they get one last chance?"
In Tauranga, where Mr Peters is trying to regain his seat from National after losing it to Bob Clarkson in 2005, a billboard was erected this morning.
It features a photograph of Mr Peters holding up his infamous "No" sign but it now reads: "No cheques, cash only".
Mr Peters held up the sign at a press conference where he denied getting a $100,000 cheque from billionaire Owen Glenn. There was a donation and Mr Glenn says Mr Peters asked for the money.
The billboard was thought up by right-wing blogger David Farrar and is not an official National Party ad.
Labour has been running ads focusing on different stances National leader John Key has taken.
The ads use quotes from Mr Key accompanied by pictures of him and then ask: "Can you really trust John or John in the tough times ahead?"
National has not targeted Prime Minister Helen Clark in its campaign.
