Later in the day, both Australian and New Zealand personnel will attend a Soldiers' Dinner, which Corp Seconi said was held annually, although it was more pertinent when on deployment and away from home.
Corp Seconi is an infantry section commander, in charge of eight soldiers from the 1st Battalion (Linton) of the Royal New Zealand Infantry Regiment.
"I remember it being an enjoyable day when I was in the Solomon Islands, so I'll be trying to recreate that," he said.
It's now the rainy season in East Timor, so the afternoons are characterised by heavy downpours, but the temperature can still peak at 38C.
Like the rest of the troops stationed in Dili, Corp Seconi will be making use of the communications set-up at the base to call his parents, Sue and Pat from Wanganui, on Christmas Day.
In 1999, Indonesia relinquished control of East Timor, and it became the first new sovereign state of the 21st century on May 20, 2002.
Since then, the New Zealand Defence Force has supported operations there, with 75 NZDF members currently deployed to Dili to help the Government, army and police, alongside about 400 Australian Defence Force members.
Corp Seconi said a typical day began with an hour of exercise, followed by breakfast, and then units headed out to patrol areas of Dili, speaking with locals and providing a visible military presence.
