He will travel with the side to Melbourne for next Thursday's 1st Lipovitan-D Rugby Championship and Bledisloe Cup Test with Australia.
Jacobson, a former New Zealand-Under 20s captain, got to Japan with the All Blacks for the 2019 Rugby World Cup but was forced home with delayed onset of concussion before playing a game.
He has played sporadically for the All Blacks since 2019, having appeared in 12 Tests, but he missed selection in the earlier All Blacks squads this year.
His chance comes after Shannon Frizell, the player who replaced him at the World Cup, suffered a rib injury in the 53-3 win over Argentina.
"It was very disappointing missing out first up, but it's been enjoyable playing for Waikato," he said.
"In the back of my mind, I always wanted to be back in the All Blacks. That's where all New Zealand rugby players strive to be.
"They've been doing it a little tough lately, but I'm sure they'll be growing closer together as a team, which I think you can see from the outside looking in. I'm looking forward to getting amongst it and offering what I have.
"You can say it's a high-pressure [environment], but it's where every New Zealand rugby player wants to be, and that's one of the things that comes with it, unfortunately, and you just take it on the chin."
Jacobson said his defensive ability was probably the asset that first saw him selected for the All Black. Issues with concussion had created a perception that he may have backed off in that area, but, with improved confidence, he has stepped back up and looks to make more impact in the contact zone.
Foster told him after he missed out on the team earlier this year to up his attacking game by being more of a threat in the wider channels. He has been pursuing that with the Waikato side that is making such an impact in the Bunnings NPC.
"I'm not expecting anything going in there, and will just be looking to take the opportunity with both hands. If I do manage to get named, I feel like I can go in and give it my best crack with nothing to lose. So that's what I'll do."
He's not unfamiliar with new forwards coach Jason Ryan as he was part of the New Zealand U-20 set-up when Jacobson played.
He was also delighted that Chiefs captain and team-mate Sam Cane performed well at the weekend. He knew the way he led the Chiefs on and off the field.
"He's a bloody good player in my eyes and one of my role models coming in at the Chiefs and hopefully long may it last which I'm sure it will."
