The former Couplands bakery site at 644 Great King St has been confirmed as the home of the restaurant, which offers Mexican-inspired fare such as tacos, burritos and quesadillas.
The eatery will be the third Taco Bell to open in the South Island.
A Christchurch location opened in July and another is due to open in the city next month.
The new restaurants are part of a push by operator Restaurant Brands to have more than 25 locations by 2024.
About 30 jobs will be created by the restaurant.
A land use consent for the site was granted in June last year, and allows seating for 30 people and 12 on-site car parks.
The maximum allowable opening hours will be 6am to 11pm Sunday to Thursday, and extended evening hours to midnight on Friday and Saturday.
The restaurant will retain the facade of the building, which operated as a garage and service station between 1947 and 2006 before being converted to a bakery.
