Registered nurse Lauren Bransgrove made an emotional public apology for the video yesterday in a statement provided to the Otago Daily Times.
She said fear rather than reason drove her to post the video on social media app Telegram, in which she called medical professionals taking part in the vaccine rollout her "enemies".
Ms Bransgrove, who used the pseudonym Lauren Hill in the video, was reluctant to speak further, but in a short conversation with the ODT said the decision to post the video had "already destroyed my family".
In her statement she said she was a law-abiding parent who let her emotions get the better of her and she would ensure it did not happen again.
"I am wholeheartedly sorry to all."
She said when she read about the vaccine rollout to young people using buses at schools she became emotional and responded without taking time to consider the effect of her reaction.
"Being a parent of two children within the affected age group, my fear drove my response rather than my reason."
She tried to remove the video the morning after the post, but was not successful, she said.
"Although I have concerns about the safety of this vaccine, I need to show respect for those who choose to have their children vaccinated and to those that are providing the vaccines."
RNZ reported multiple agencies were investigating after the registered nurse posted the video and she has been referred to a professional conduct committee by the Nursing Council.
On her LinkedIn, Ms Bransgrove is listed as working as a clinical adviser at ACC.
ACC chief executive Megan Main told the ODT it was "urgently investigating" the matter.
It was introducing a policy requiring all staff at ACC sites across the country to be vaccinated from today.
In the video, Ms Bransgrove called on fellow anti-vaxxers — referring to them as "the resistance" — to organise and prepare to monitor schools every day so they could attack vaccination buses when they turned up.
