The Southland prop and captain had brother Andrew's 22nd birthday to mark on Saturday night and then his mother, Kate, had a birthday yesterday.
But the icing on the cake was being named yesterday as one of seven new caps in the 35-strong All Black squad for the upcoming Grand Slam tour.
"I'm pretty thrilled with the call-up. We had a good night at home last night and a good day," Mackintosh said from his Tokonui home yesterday.
"Everyone was at home and then the neighbours came around this morning. We had about 20 there. By the time I had to go to the airport we had to call the Tokanui Tavern courtesy coach, as no-one else could take me."
So the Mackintosh family piled into the van, along with the new All Black, to go to Invercargill Airport to say goodbye to their boy, Southland's 55th All Black.
Mackintosh (23), who is tipped to captain the Highlanders next year, said he did not go overboard in celebrations and, despite being picked by most pundits, the 128kg man nicknamed "Whopper" had some nervous moments on Saturday night.
"I watched the [Air New Zealand Cup final] on Saturday night and I thought Wyatt [Canterbury prop Wyatt Crockett] had a pretty good game."
The loosehead prop cannot wait to get on tour.
"I just want to learn as much as I can from the likes of Mike Cron and Tony Woodcock."
Otago's sole representative in the side is loose forward Adam Thomson, who retained his place in the All Blacks squad.
Thomson (26) said he had been told by the All Blacks selectors he was seen as a blindside flanker and as a back-up at openside flanker.
A 60-minute blow-out last week in a match at a training camp in Auckland had helped get rid of his cobwebs, he said.
He was looking forward to his first northern hemisphere tour with the national side.
