Jacinda Ardern has given the opening address at national tech as a hologram.
As she was unable to attend Techweek in person, she appeared as a virtual version on stage.
According to the organisers of the Techweek event, it makes her the first world leader to use the technology.
Ms Ardern is not the first politician though to have a virtual version of herself as a stand-in.
In 2014, now-Prime Minister of India Narendra Modi used projections of himself with holographic effects during his election campaign to address rallies.
