Davinder Singh was found not guilty on the charge he faced, and was acquitted.
Charges against another man, Harmish Singh, were dropped mid-way through the trial and he was discharged.
Justice Mark Woolford remanded all those who were found guilty on bail until sentencing in February.
During the trial, Crown prosecutor Robin McCoubrey told the court that Daljit Singh falsely changed the addresses of a large number of people on the Electoral Enrolment Centre's website before the 2010 election so they were registered as living within the boundaries of the Otara-Papatoetoe Local Board.
Most were Sikhs with the surname Singh, or Kaur for the women, and many were unaware their details had been changed.
Mr McCoubrey said the enrolment centre contacted the police when it noticed a large number of names were being registered in the electorate and that forms were being downloaded from computers that had the same IP addresses.
The Crown alleged the seven others helped Daljit Singh, some by providing him with personal details of people who lived outside Auckland.
Singh is a real estate agent, marriage celebrant and licensed immigration adviser.
He is also a spokesman for the New Zealand Sikh Society and convener of the Supreme Sikh Council.
He did not receive enough votes to be elected to the local board, and was arrested in the days before polling closed.
A police investigation was launched after more than 300 people were removed from the electoral roll due to irregularities, and it was reported that 48 were registered as living at one address.
