An "incredibly disappointed" Rose Matafeo has spoken out on Twitter about allegedly losing an MC role at the Green Party campaign launch at the request of Golriz Ghahraman.
The comedian and actor was previously in a relationship with Guy Williams, who is the current partner of Ghahraman.
Matafeo said in tweets she still intends to vote Green in the upcoming election, but she's "gutted" and "disillusioned" at not being told why she was asked to step down.
The Green Party has put the situation down to a "miscommunication" and says it wants to talk to Matafeo privately about it.
"Feel incredibly disappointed to be asked to step down from MCing the Green Party campaign launch, apparently at the request of one of their MPs," said Matafeo.
"I have no relationship with this person, so am feeling a little confused. I reached out last week to ask why and still have had no response. Gutting! Still gonna vote Green though.
"Not being able to volunteer my (very few) skills because someone in their ranks does not personally like me makes me feel sad and disillusioned."
The Green Party has described the situation as "unfortunate".
"MPs aren't involved in organising party events or arranging speakers," a spokesperson for the party told Newshub.
"Unfortunately, this seems to be the result of a miscommunication within the party. We are more than happy to discuss this with Ms Matafeo personally."
One of the tweets included a screenshot of an email to Ghahraman asking for more information.
In the email, Matafeo says: "Yesterday I was notified I have been asked to step down as an MC at the upcoming Green Party launch, at the request of Golriz. I'm unsure why this request was made, as I have had very little interaction with Golriz in the past few years."
Replies to the tweets have mentioned Matafeo's previous relationship with Williams and in one of her own follow-up tweets she added: "The only possible reason it could be is so petty that I wouldn't dream of suggesting it."
Meanwhile, fellow comedian Tim Batt announced on Facebook on Sunday that he would be MCing at the Green Party event.
Matafeo had no further comment when approached by Newshub.
