The $11 million second stage of the new Braemar Hospital is almost complete - with just six weeks until the first patient can check in.

The completion of the second stage will finally bring the hospital together at one site.

While the new $30 million first phase of the private hospital - on the corner of Ohaupo Rd and Kahikatea Dr - opened in 2009, its Day Hospital remained at a leased building in Knox St.

But the opening of the new stage - which opens to patients mid-September - will allow them to move all operations under one roof.

"So all the beds and equipment will come up here [to Ohaupo Rd]," finance manager Brenda Williamson said.

"It's going to be very nice for both specialists and staff to all be on one site."

It would also reduce confusion among patients and visitors.

The new phase would see the addition of an ambulance bay - so patients will no longer have to enter the hospital via the reception area - two more operating theatres, two endoscopy suites and 20 more beds.

This adds to its current 60 beds, six operating theatres and five ICU beds.

The hospital will have 100 beds and 11 operating theatres by the end of phase three - due for completion in about three years.

Chief executive Paul Bennett said he was looking forward to that day.

"I think I'll go fishing," he said.

Mr Bennett said the second phase had come in on time and budget.

It had also gone a lot smoother than the first, from which they learnt a lot.

"But we got it about 98 per cent right with phase one. The 2 per cent was nothing in terms of patient care, it was more things like the way an office was set up or silly things like locks on doors. Just minor stuff. The patients still had the same standard of care."

Braemar will hold an open day, and official opening, on September 28.

David and John Young - the two adopted sons of Sister Francis Young who set up the hospital in 1926 - will be there to cut the ribbon.
