Lucia Echaniz, of Argentina, was the only one to give the oath of allegiance in te reo Maori at the Queenstown event.
Ms Echaniz, who is studying health and wellbeing at the Southern Institute of Technology in the resort, said one of her teachers urged her to do it.
"So I knew I had to stand up today.
"I don’t consider myself to be brave. It should be normal."
She received her certificate and native tree alongside her partner, Agustin Mortola.
The couple have a special connection to Queenstown, having met 13 years ago while living in the resort as work visa holders.
After returning to Argentina, they decided they wanted to return to New Zealand to live, Ms Echaniz said.
They did so nine years ago, and had been living in the resort for the past six.
"We’re so grateful. We share the values of Aotearoa, and the face of New Zealand is changing.
"New Zealand is an open-minded, bicultural country.
"That makes it easy for us. We feel at home."
Their son, Teo, was born in New Zealand three years ago.
"He was the first Kiwi in our family."
Mr Mortola, a chef, said they both "fell in love" with New Zealand soon after they first arrived, especially with its people and culture.
Tuesday’s event was so big because 50 of those attending became citizens last year, but a ceremony could not be held because of Covid-19 restrictions.
