At the end of March, as the coronavirus began to increase its spread through New Zealand, Invercargill couple Betty and Manoli held their wedding reception at Bluff.
"Amazing day, all our family around us," Betty says. "Then it all changed."
One of the guests had the virus - and they had passed it to the group.
Both Betty and Manoli fell ill to COVID-19 - and so did Manoli's dad. He passed away several days later in hospital.
By tracing the Bluff cluster virus' genetic history, scientists could determine it likely came from New York. Contact tracing established it was brought into New Zealand by a flight attendant.
"The flight attendant, from what I understand, was on a flight from LA to New Zealand and so it's probably likely that someone from New York boarded a flight to LA and perhaps even got on that flight from LA to New Zealand while infecting the flight attendant," Otago University evolutionary virologist Dr Jemma Geoghegan tells Newshub National Correspondent Patrick Gower for his On Lockdown documentary.
The flight attendant is a very close family friend of Manoli and Betty and had no symptoms before the wedding. But the couple say the only blame is with the virus.
"I'm not going to blame no one," Manoli says.
"I want to look back on that day. Not everything else that happened afterwards," Betty says.
