Instead of the usual breakfast in bed and card from his children on Father's Day, Staff Sergeant Kirkland will be at work at the Taji Military Complex, 20km outside Baghdad in Iraq.
But he said he was looking forward to opening the Father's Day package his family had sent.
"I've heard they'll send something over – hopefully it's some Weet-Bix. I'll feel loved with some Weet-Bix," he said.
New Zealand Defence Force (NZDF) soldiers serving in Iraq will be relying on technology to connect with their families on Father's Day tomorrow.
About 30 Kiwi fathers are deployed with Task Group Taji, the combined New Zealand-Australian task group that is in Iraq to help train the Iraqi Security Forces for their fight against the Islamic State (IS) terrorist group.
Staff Sergeant James Kirkland, who works in the Task Group workshop, is on his second deployment since having children and said it had been tough being away from his two daughters and fiancée.
"It's definitely pretty hard. This is the longest I've spent away from them," he said.
For Operations Officer Captain James Brosnan, this is his first Father's Day away from his 1-year-old daughter and wife.
"It really hasn't sunk in yet but when the day comes around I'll think about all the things I've been missing," he said.
Advances in communication technology had made the separation easier, he said.
"The technology now definitely keeps me in touch with what's happening and how she is growing up."
Lieutenant Roger Baxter will also be video-calling his wife and children on Sunday. The Task Group Taji Watchkeeper has three children – two adults and a teenager.
Although he has been away for some Father's Days in the past, this is the first time he has been overseas on deployment for one.
"I was a bit teary when I thought, Father's Day, and I'm away for it," he said.
While his family is more than 15,000km away, he said the distance hadn't affected their strong bond.
"The farther away we are in distance the closer we seem to have become as a family," he said.
About 100 NZDF and 300 Australian Defence Force personnel comprise Task Group Taji.
