Host Ben Fordham was quick to pick up on Pyne's blunder, and asked the MP if he meant to say that.
Fellow panellist Labor frontbencher Anthony Albanese also attempted to correct his Liberal counterpart, but he seemed to suggesting her name was "Jacinta".
After bemused looks and laughter from Fordham and Albanese, Pyne corrected himself.
"I'm having one of those mornings," Pyne said.
And it seems even Labour Party members have struggled.
Ardern herself did not notice the error until media brought it to her attention.
"Oh, they are missing an 'r'. Hilarious! Common. Very very common," she said.
"I hope they keep it that way."
Why? "Because the day that Norman Kirk opened those rooms, a seagull pooped on him. So there's got to be something that happens to me. A misspelling is probably better."
