Waikato Hospital says a new $130 million clinical centre will provide more than 100 jobs and allow staff to carry out more operations.
The district health board says the centre includes a dozen operating theatres that will open in July this year and new suites for treating cardiac patients.
The DHB says it has hired doctors and anaesthetists, and is now advertising for more than 100 nurses, technicians and healthcare assistants.
Project manager Aileen McGowan says extra theatres and new technology means the hospital can start performing surgery that it has had to outsource to other hospitals.
"We've been outsourcing a lot of our operations to private providers while we've been constructing the med clinical centre and this is bringing back the outsourcing of elective operations," she said on Monday.
The board's building programme at Waikato and Thames hospitals, which began in 2005, is due to end next year.
