A tax rebate scheme's helped boost the number of people employed in the video game sector by more than 20%. 

The four-year, $160 million Game Development Sector Rebate allows eligible studios to claim back 20% of their spend.  

Forty studios will receive a share of $22.4 million this year, for its second year. 

Game Development Association Executive Director Joy Keene told Andrew Dickens the sector's booming compared to a few years ago. 

She says it's been a game-changer, as a lot of New Zealand studios were looking to move to Australia because of their rebate.
