Kim Dotcom was welcomed to the stage as New Zealand's "newest super hero".
"I can tell you right now we will get over 5 per cent in this election," he said.
Dotcom had a message for John Key: "We are going to stop your National disaster."
He said as a 19-year-old he hacked the German credit rater because he wanted to ruin the German's Prime Minister's credit rating and hacked in to Nasa to find out if aliens existed.
He said he was given a second chance by a judge because they saw potential in his offending.
He said he wanted to give other young New Zealanders that chance.
"There is no rock star economy in New Zealand and there will be no rock star economy under National," he said.
"We're going to take this country forward and take this country back from the Americans."

Dotcom introduced Laila Harre as an "amazing leader".
"She has given us a voice and she is going to take us over 5 per cent and into government."
Ms Harre acknowledged the "humanity, compassion and capacity for sheer hard work" of Hone Harawira and Dotcom.
"Today is a celebration of the possible," she said.
Ms Harre announced the goal of achieving of full employment for the country to a round of enthusiastic applause from the audience.
"The management of unemployment is a dead end street," she said.
"The solution does not lie in punishing the unemployed ... The solution lies in full employment."
If in government, internet Mana would spend $1.1 billon a year for the next five years to create short term jobs for young people, young single parents, people who have been unemployed for a long time and for students, Ms Harre said.
A specialised digital workforce would create 50,000 new permanent jobs in the next five years, she said.
"And this is all addition to our plans to reintroduce free tertiary education."
A programme to take away student loan debt would also be introduced, she said.
Ms Harre compared early governments' commitment to developing pastoral farming to Internet Mana's commitment to growing a digital workforce in New Zealand.
She said internet Mana would open the government up to public scrutiny.
She urged the audience to create a "true MMP government".
Internet Mana would start a campaign to stop the Trans-Pacific Partnership agreement, she said.
Annette Sykes was welcomed to the stage with a standing ovation from many members of the audience.
Ms Sykes said Hone Harawira had asked her to deliver the policy speech after he was in a car accident.
Mr Harawira had been asked to take it easy and would only be at the campaign launch for the later part, she said.
Ms Sykes said eliminating child poverty must be on the mind of the government, and asked how it could commit to backing Team New Zealand while children go hungry.
"We are abolishing charter schools and taking the money they're putting to charter schools and giving it to Kura Kaupapa Maori," she said.
Her speech had the audience cheering "kia ora" and stamping their feet.
She finished by announcing that Mr Harawira had arrived, and passing over to "our beloved leader" or "King Hone".
Mr Harawira gave a brief speech saying "our aim is to change the government."
He handed over to his son who stole the show with a freestyle rap about Internet Mana.
Mr Harawira said after the campaign launch he could be facing a charge of careless use of a vehicle for his car crash.
He said he lost control of a rental car on the Mangamuka Hills, flipped the car and ended up down a bank where the car landed on its roof.
"I'm very lucky to be alive," he said.
He said he was happy to have Ms Sykes deliver the speech for Mana.
"I'm really comfortable I have people like Annette, Laila, John Minto who can deliver the kaupapa."
