"This time I have 14 weeks, I will take this seat by a majority of more than 1800," Ms Sykes said.
Mr Harawira said: "She never got much of a shot last time. We were rushing around trying to save the world all at once. Parliament will be changed forever when she comes in on September 21."
Ms Sykes said she proposed to make a strong stand as a Maori woman and support her people as an advocate.
She was questioned on the relationship her party had with Mr Dotcom's Internet Party.
"I have a clear conscience working with someone who has disclosed to us his past," she said.
"I wish John Key would disclose to us what he is doing in the present, same with Judith Collins, who did they talk to in China?
"The Internet Party has announced two policies that are absolutely cutting edge, like Mana is."
These were a privacy policy to disestablish Government spy agency GCSB and an environmental policy opposing deep sea oil drilling.
Mr Dotcom said he was disappointed not to make it to Rotorua as planned.
"I was going to use the opportunity of being in Rotorua with senior members of the Mana Party executive to continue discussing the ways the Internet Party and Mana Movement can work together.
"Those discussions are well advanced and we will now find other opportunities to carry forward the discussions."
Mr Flavell will bid for re-election while Rawiri Waititi is the Labour Party's candidate for the Waiariki seat.
Meanwhile, New Zealand First's Fletcher Tabuteau is the only person nominated by his party to stand in the Rotorua electorate but his nomination still needs to be confirmed.
The branch held its AGM in Rotorua this weekend. Leader Winston Peters spoke to just under 100 people.
