Half a dozen staff from MFAT's America's division in Wellington will work with staff in Washington on the task force, which will likely be in operation for several months.
"This is not (business as usual) at the moment and I think we need to be running this as a 24/7 operation which means being able to give the government advice in real time," Barrington said.
He said 1220 staff had to be appointed to roles within the new US administration, something that he understood took former president Barack Obama five or six months to do so.
"I'll keep (the task force) in place for as long as it's needed," he said.
Barrington said the task force was not solely a response to Trump's election, but is the way a modern foreign ministry should operate these days.
