The data of more than 60,000 New Zealanders may have been taken alongside 87 million people worldwide in the Cambridge Analytica scandal.
It's believed only 10 New Zealanders downloaded a quiz app, which led to around 64,000 friends' data being compromised.
Newstalk ZB presenter Heather Du Plessis-Allan was one of those who downloaded the app - and is awaiting confirmation on whether she is one of the 10 duped.
She wasn't certain if or how much information had been taken from her Facebook account.
"What happened was I was at university last year and one of my lecturers was talking to me about the possibility that Cambridge Analytica had actually been involved in the New Zealand election so I went and did the personality test," she said.
"I don't know for certain how much information they would have gotten off my Facebook, or even if they did, but I am assuming they took my stuff and my boss' because he is my friend on Facebook."
Every Facebook account holder will be sent one of two notices informing them whether their data was breached.
The notices will either display the means of "protecting your information", or other users will see a message telling them their data may have been shared.
Du Plessis-Allan, who is also a Herald on Sunday columnist, said she has not yet received a message, but she has apologised to her 200 or so friends on Facebook in advance.
"I am waiting for New Zealand Facebook users to start getting these notifications so I will know for sure if I am one of those 10," she said.
She said she didn't really care if her data had been taken, and none of her friends had voiced any concerns.
"Let's assume it is the Russians that got a hold of it, or Cambridge Analytica, but what are they going to do with my data?
"They are welcome to it. There is nothing on there and I sincerely hope my friends haven't put anything too interesting on their Facebook pages too now they know.
"The problem for me is with the principle of Facebook allowing this to happen, the principle of Cambridge being involved, and of Cambridge Analytica doing this.
"It is more the principle of the data breach that is the problem here."
The Privacy Commissioner hasn't yet decided whether to launch an investigation into the data breach.
