A spokesperson for the commission said the Serious Fraud Office passed on the complaint.
The Electoral Commission can look into a complaint, but will pass it to the police if they believe there is any wrongdoing.
Te Kahika's party has formed an alliance with former National MP Jami-Lee Ross' Advance New Zealand Party.
