He believed the complaint was an act of "revenge" by Bevan Chuang - the former mistress of ex-Auckland Mayor Len Brown - after Kang had turned down a $10,000 offer by her to run his campaign.
The commission said it had received more than one complaint alleging Kang's campaign offered "hong bao dollars" or online money envelopes on WeChat.
When contacted by the Herald, Chuang admitted to being one of the complainants.
However, Chuang claimed it was she who rejected Kang's "cash offer" to be part of his campaign rather than the other way around.
"They [Kang's campaign] were sending out red packets on WeChat, and my complaint was just to question whether that is legally acceptable," she said.
Her complaint alleged red envelopes were first offered to a WeChat group consisting of hundreds of members to distribute a Chinese news report on Kang on August 20.
Later that day, a man linked to the campaign sent out the virtual envelopes to the group to promote the candidate as someone who is "speaking on behalf of Chinese".
A second round of virtual red money envelopes were also allegedly sent out a week later on August 27.
The Electoral Act 1993 forbids bribes or treats in exchange for votes.
Kang, who did not speak at the conference, said he would not comment and added that he did not wish to speak to the Herald.
A Maori Party spokeswoman said: "The value we've calculated so far is equivalent to $0.15 cents per person in the group."
Hong bao is a Chinese tradition of gifting money in a red envelope usually on special occasions, and was adopted for the digital age when WeChat introduced the ability to distribute virtual red envelopes of money to contacts and groups via its mobile platform for the 2014 Chinese New Year.
Users of the app can send money in the form of virtual credits to other users of the application. Money is deposited into a user's WeChat Pay account, which can be used for purchases. The app allows withdrawals from that account.
Earlier today, the Electoral Commission apologised, after it emerged it had given sensitive information relating to the investigation to Kang.
Screenshots which identified the person who took them were inadvertently provided to Kang and his team, a commission spokeswoman said.
"Screenshots were provided that inadvertently identified the person who made the screenshots, and we have apologised for this," she said.
The commission does not identify individuals in relation to complaints, the spokeswoman said, and that it was "regrettable" that this has occurred.
"Mr Kang has been informed that the person identified is not the person who made the complaint," she said.
"And that the Commission has received queries about the same matter from more than one person."
Kang was announced by the party a last month as its first Asian candidate and its candidate for Botany.
He is a beekeeper and a former pharmacist, and has been asked by the party to stop using WeChat.
