Hone Harawira's son is facing a number of charges, including wilful damage and threatening behaviour.
The news comes after it was revealed that three of the Mana Party leader's nephews are also facing charges of injuring with intent to injure.
Mau Toa Harawira, Enesi Zane Brooks Taito and Tohora Harawira allegedly assaulted a 12-year-old boy in an incident in August last year.
Now ONE News can confirm even more of the Harawira family are facing charges ranging from assault to aggravated robbery.
Hone Harawira's son Hone Puripiri Harawira, 38, is due in court next week accused of wilful damage and threatening behaviour.
He has also been charged with assault with a weapon in a separate case.
Hone Harawira is refusing to comment but sources close to the family say he is furious and was not made aware of all of the alleged offending until recent days.
Another of Hone Harawira's nephews and a well-known activist at Waitangi, Wi Popata, is also charged with aggravated robbery, grievous bodily harm and three charges of aggravated assault.
Ngapuhi elder, Kingi Taurua, told ONE News the allegations are causing a stir in Hone Harawira's Te Tai Tokerau electorate.
"There are some people who are saying to me that they are not sure whether Hone and his family are the right people to be representing this particular area," he said.
However, others sympathise with him.
"Sometimes it's very unfair to have the actions of a relative to be invested upon you but that's the nature of public life sad to say," said New Zealand First leader Winston Peters.
