David Fisher: NZ Herald investigative reporter on the confidential report into Shane Christie's concussion care - Heather du Plessis-Allan Drive

Before he died, rugby star Shane Christie sent a secret NZ Rugby report to the NZ Herald, claiming its findings needed to be released to keep future rugby players safe.

The report describes a detailed safety-net of measures Christie insisted be explored in the hope NZ Rugby would improve player safety.

NZ Herald investigative reporter David Fisher received the report - and he weighed in on the secrecy around the data.

"There were many things that were raised in there that Shane was very keen to have explored."
