NSW Police Commissioner Mick Fuller has hit back immediately against a coroner's findings into music festivals, saying any suggestion his officers contributed to the drug-related deaths of six young revellers "will be strongly defended by me."

The state's most senior police officer issued a statement backing law enforcement tactics at music festivals soon after a coroner released a set of findings over the spate of recent deaths that said policing methods at events potentially harmed punters rather than protected them.

Deputy State Coroner Harriet Grahame called for policing at music festivals to be drastically rolled back, recommending that the use of sniffer dogs be scrapped and strip searching be constrained.

She urged Mr Fuller to direct his officers against taking a punitive approach to drug possession for personal use and rather concentrate operations on organised drug dealing, social disorder and other crimes.
