Prime Minister John Key has continued to needle Phil Goff over his economic plans while campaigning in Auckland today.



Last night in a heated leaders' debate, hosted by the Press, Key told Goff to ''show me the money'' and provide detailed costings for his party's proposals. He said Labour had to find at least $14 billionn to pay for election pledges.



Goff has promised to tomorrow release the spreadsheet that Key taunted him over during the debate.



In Auckland today, Key turned up the heat, suggesting Labour would ramp up Emissions Trading Scheme costs for businesses.



''I think New Zealander will be very worried about what hey saw from Phil Goff last night. We are now three weeks and a couple of days from the election. There's no costings from Labour.

"He can't go around saying he is going to balance the books earlier and claim the moral high ground with things like the Capital Gains Tax and raising the age of the Super.''



As in last night's debate, he accused Goff of ''not being honest.''

''If they are going to balance the books then a new tax has to be coming from Labour.



''I think they are going to borrow a bit more ...and I think they are going to fudge the numbers when the eventually come out and claim some magical growth dividend...they will play with funny money, I think.



''I wonder if they are going to ramp up the ETS and hugely put up the costs of power, I mean that is a possibility. They could really sock it to the consumer in a big way. They have got to have something...they've just got to tell us.''



Key was in Auckland to announce a multi-million dollar advanced technology institute.



He was also forced to defend his government over the latest jobless totals, up to 6.6 per cent in the September quarter.



In Auckland, Key went walkabout in Ponsonby Road with Auckland Central candidate Nikki Kaye and visited the Canon/Datacom call centre in Northcote, with local MP Jonathan Coleman.

ATTACK EXPECTED

Goff today admitted he was beaten by Key over aspects of the economy in the head to head debate last night.



''Key was able to invent a lie, which was wrong, but to invent it without our ability to put on the table our actual figures,'' Goff said.



''We have done those figures, we're just completing them now as we've finalised the last of our policies.''



Goff said he had expected the attack from Key, but it was important the party did it right.



''You put your costings out when you've finalised your policies,'' he said.



But National's associate finance spokesman and campaign chair Steven Joyce said Goff had failed to explain how Labour would account for a $17.2b hole in the accounts within four years.



''Three weeks out from an election, New Zealanders will be appalled that the Labour leader does not know how his party will pay for its promises,'' Joyce said.



''Either that, or he's hiding a deep dark secret that will involve extra borrowing, or even higher taxes on hardworking Kiwis.''



Goff said the debate had been a game of two halves.



''We won on the Christchurch earthquake, I think we won clearly on asset sales and about reducing the gap between rich and poor in New Zealand,'' he said.



He admitted Key had the edge when it came to the economy.
