Police on Thursday said the campaign included videos with advice on how to report a hate crime as a victim or witness.
There were also print materials, in five languages, for display in police stations, government and council offices and local businesses, police said in statement.
The launch comes after spikes since COVID-19 in prejudice against Asian, Indigenous, Jewish and Muslim groups triggered calls for new measures to combat racism.
NSW Police Assistant Commissioner Mark Walton said research showed only 25 per cent of hate crime victims sought police assistance.
"We know there is a significant disparity between the number of hate crimes that occur and the number reported to police," Mr Walton said.
"The impact of a hate crimes and incidents are usually felt beyond just the immediate target. More often than not, it will extend to families, friends, and throughout communities.
"NSW is a diverse collection of communities, and we all need to make it clear that we do not tolerate or accept crimes or incidents based on bias or hate."
The campaign was developed by the police's hate crime unit in consultation with community groups.
The Australian Hate Crime Network, part of Sydney University, has previously said the problem impacts groups such as the Asian community as well as Jewish, Muslim, disabled and LGBTQI people.
