The extra tickets were announced by organisers yesterday after the event was moved from the Emirates arena to The Hydro in Glasgow, which has double the number of seats.
The tickets went on sale for the gold and bronze medal matches at 11am today and were quickly bought by fans. The netball final will be held on the last day of the Games.
Glasgow 2014 chief executive David Grevemberg said: "It's a real thrill to see tickets for this world-class showcase for netball being snapped up so quickly.
"What a great vote of support for Glasgow 2014 and the sport of netball and (it) brings with it a fantastic opportunity to see the game played at the highest levels by its global stars."
Some 2.3 million requests were made for up to one million tickets when the application process opened last year. Some of the events at the Games were massively over-subscribed and Glasgow 2014 allocated tickets via a draw.
More than 100,000 applications were made for the 100m men's final at Hampden Park, with track cycling, diving and artistic gymnastics among the other sports over-subscribed.
Thousands of free tickets have also been given away to young people, sports volunteers and disabled groups.
Organisers said around 95% of tickets have been sold with some remaining for sports including badminton, boxing, bowls, rugby sevens and the opening and closing ceremonies.
