The 54-year-old MP wasn't talking about the picture. "You don't even feel it," he said.
He said that despite the role of MPs, it would not have been a "great look" to pretend to be "someone special" when it came to getting the vaccine.
Wife Sarah is set for her appointment, and he expects his 19-year-old daughter in Auckland and 16-year-old son in Napier to follow as the programme steps up throughout the country.
There hadn't been a specific direction to MPs about when to get their vaccine, other than that he got the text message from "the system" as the next group was opened up last week and made the booking.
Aware some people have not found the booking process quite so simple, he said if on-line processes weren't helping, people should "ring the number and get it done".
"I wouldn't have wanted to be seen as jumping the queue," he said. "It would have been horrible."
As it happens, not even director general of health Ashley Bloomfield has yet had the vaccine.
Nash's appointment came on the second day of the new level 4 lockdown, and just a couple of hours after the daily update that said a one-day record of 195,537 people had made their bookings the previous day.
