After the barbecue, which includes a Pacific performance for Mr Goff, he will visit some RSA clubs, go to housie, and meet with night cleaners until midnight.
Under electoral law, nobody can campaign on election day itself or do anything to try to sway voters.
It means all billboards, hoardings, car signage and signs must be taken away or hidden away.
Mr Goff's voice was starting to get hoarse by mid-afternoon, but he was confident it would hold out until midnight.
Earlier this afternoon, he was entertained in Hamilton West by a school group from Nawton Primary on a brief stop over.
There was an amusing moment when Mr Goff stood to speak just as they finished, only to be quickly silenced by one of the group calling a command to the rest of the singers.
The sheepish look on his face made the gathering laugh before he was allowed to speak.
He covered poverty in his brief address, saying that even Prime Minister John Key had admitted he could not live on a minimum wage of $13 an hour.
Abuse of power
Goff has also cautioned voters not to let National get an absolute majority this election, saying he believes they will "abuse" such power and sell off entire state assets.
Mr Goff stood on the banks of Karapiro dam, near Cambridge, for the second visit in his whistle stop tour of dams and power stations in the upper North Island to highlight his message against state asset sales. The first was at Mangakino earlier this morning.
Although there are few voters to actually sway at the dams, Mr Goff has interspersed them among his more public appearances to ensure the message in the heads of voters when they go to bed tonight is Labour's warning about state assets.
National has said it will only sell up to 49 per cent of four state energy companies. Speaking to about 25 Labour supporters waiting at the Mighty River Power dam in Karapiro, Mr Goff said he did not believe them.
"John Key's going around saying 'give me an absolute majority.' If New Zealanders did that, we wouldn't just lose half the assets - we'd lose the lot."
Mr Goff said National would not have a mandate for any asset sales, regardless of the election night result, because public opposition to the policy was clear.
"We are focussing solely on tomorrow and maximising the Labour vote, making sure National don't get a majority and don't get an absolute majority. If they get an absolute majority, they will abuse it and sell the whole of our assets."
Mr Goff has met some voters today - he stopped for a brief walkabout in Tokoroa, where he signed a Salvation Army petition and brought a sausage from a White Ribbon day fundraiser. He also got a sneaky endorsement from the band playing on the street side: its singer announced Mr Goff was there and added "I'm not telling you how to vote, but my name is Red."
Mr Goff also spoke about the cost of living, saying new Statistics NZ figures showed rent and other costs had increased beyond real wage increases.
