We've got enough James Bonds...what the country needs now is more Jane Bonds.

The GCSB is expanding after getting an increase in its budget...and its focus now is gender balance.

More than half the leadership team at the country's spy agency are women, but they want more female staff.

The GCSB is encouraging women to study STEM subjects, science, technology, engineering and maths and consider a career in cyber security.

It's awarded four $10,000 tertiary scholarships to women studying those subjects at New Zealand universities.

Director general Andrew Hampton said they also run a graduate programme.

"We are also after people with liberal arts degrees, people who are good writer and thinkers as well."

He said about 35 percent of the GCSB workforce are women.

"About 60 percent of our leaders are female which is great but we are very committed to getting more women to come and work for us particularly women with backgrounds in those stem subjects, science, technology, engineering, and mathematics."
