There's suggestions of a deep divide within Te Pāti Māori.

The Party's released documents to members alleging former vice president Eru Kapa-Kingi threatened parliamentary staff and made inappropriate remarks. 

He's the son of recently demoted Party Whip, MP Mariameno Kapa-Kingi. 

Papers also showed Parliamentary Services were concerned she risked overspending her office budget. 

Political commentator Bryce Edwards says there are obviously factions. 

"This is from the leadership against the MPs in question, so this is a bit of a meltdown."
