It's not just the new owners of the old Wellington Air Traffic Control tower that will be smiling

Tommy's Real Estate, that sold the tower, is giving away its commission - making a sizeable donation to Wellington's under-construction children's hospital.

Airways New Zealand put the tower up for sale after almost 60 years of service.

Sales director Nicki Cruickshank says they'll be donating around 20-thousand dollars, so the hospital can buy some good equipment.

The tower's sold for 20-percent more than was expected ... the asking price was around 900-thousand dollars.
