Tamati Coffey has been called out after telling fellow MP Melissa Lee to "stick to your job, love".
The two television personalities-turned MPs traded barbs at the end of a select committee hearing at Parliament today.
In an exchange captured on audio, National MP Lee suggests to a staffer there should be two microphones when two Ministers appear in front of the Economic Development, Science and Innovation Committee.
But things get a little heated when Labour's Coffey weighs in.
"Hey, hey, stick to your job love," he says. "Ordering around the microphones."
