The release of a report into diversity in the intelligence community has found the SIS and GCSB are largely staffed by white males and struggle to attract Maori and Pacific people - but that comes as no surprise to the Maori Party.

Maori and Pacific staff were also found to have faced harassment through excessive and unnecessary racist jokes.

Maori Party co-leader Marama Fox says it's no surprise the agencies would struggle to attract Maori and Pacific Islanders due to the unconscious bias those communities receive from our justice system.

Ms Fox says it's not a career path Maori and Pacific people tend to gravitate towards.

"For a long time Maori and Pasifika have suffered institutionalised racism in the justice system as a whole so it's no surprise at all that they struggle to recruit people into this type of work."

She's glad the report has recognized this lack of diversity, but says the banter and racist jokes being told within the organisation need to be addressed.
