The Wellington man who died after contracting coronavirus was the father of the groom in the Bluff wedding cluster, Stuff reports.
Chrisanthos (Christo) Tzanoudakis, 87, is one of New Zealand's five deaths related to the virus.
He died in Wellington Hospital on April 10, Stuff reported.
Director of public health Dr Caroline McElnay announced the death on Saturday, and confirmed the man's infection was linked to an existing cluster that would not be identified for privacy reasons.
But director-general Dr Ashley Bloomfield later named the Bluff wedding event, held on March 21, as the cluster involved.
Tzanoudakis first started showing symptoms on March 26 and was admitted to hospital two days later.
The widower and father of two was originally from Crete and had lived in Wellington for 50 years, Stuff reported.
Tzanoudakis was also one of the founders of the Cretans Association of New Zealand, and served as the president for some years.
In a post on the organisation's Facebook page, current president Stamatis Nikitopoulos announced Tzanoudakis' death with "a heavy heart".
"Christos was born on the 8th October 1933 and migrated to New Zealand from Topolia, Kissamou, Chania, Crete in 1963 and worked at the Wellington Wharf Docks for many years," Nikitopoulos said.
"He was a very much-loved man by all his family and friends and a well-respected member of the Cretan Associations and the broader Greek Orthodox Community in Wellington."
He said Tzanoudakis' family wanted to grieve for their "loving, kindest and warmest father and grandfather".
Tzanoudakis' funeral service is being held today.
About 70 guests attended the reception at Bluff's Oyster Cove Restaurant and Bar following the wedding in Invercargill.
There are now 86 cases of Covid-19 stemming from the event. The bride, groom and several other family members have tested positive, as have about 10 staff at the bride's workplace - Invercargill City Council - according to Stuff.
Data published by the Ministry of Health shows the cluster originated from "overseas exposure" to the virus.
It's the nation's largest cluster of cases, ahead of Marist College's 85. There are 13 clusters in New Zealand with 10 or more known cases.
An Air New Zealand flight attendant is believed to have been questioned as part of investigations into how coronavirus arrived in the cluster.
The flight attendant told guests he had returned to New Zealand from a work flight from the United States just days before, according to a Herald source who did not want to be named.
He was said to be coughing and - at a gathering of family and guests the next day - was gargling salt water, apparently for a sore throat.
The Herald has learned he went on special leave from his job about March 25.
