Zakaria Bhuiya had taken annual leave on March 15 to celebrate his 34th birthday at the Masjid Al Noor Mosque, not knowing it would be his last.
He was one of 50 people killed in a horrific mass shooting that targetted two central city mosques in Christchurch.
Bhuiya was from Bangladesh and worked as a welder at AMT Mechanical in Addington to support his family.
His employer started a Givealittle page to support Bhuiya's widow Rina Akter.
"He lived on the bare basics in order to maximise the money he could send home to support his family," the Givealittle page said.
