Ms Bennett reclaimed the seat with a margin of nine votes after she requested a judicial recount. But in that case Judge John Adams ruled that he would not attempt an audit of those who were not on a roll.
Mr Harawira said the judge was wrong in that case and did have the power to review any decision of the Returning Officer or the Registrar of Electors in respect of the checking of special voting declarations; or the allowance of special votes.
"While the Returning Officer may have to accept the work of the Registrar of Electors, it is clear that your Honour does not, and the special votes rejected by the Returning Officer during the Official Count may be looked at afresh," he said.
"Irrespective of whether the recount changes the result of the election in Te Tai Tokerau, these issues need to be independently examined and substantial improvements made ahead of the next election to ensure our people's basic rights are respected and their participation in the democratic process is encouraged and affirmed."
Mr Davis said he was not surprised by Mr Harawira's actions.
"People handle defeat and loss in different ways. Hone's predictable and we expected this," Mr Davis said.
