A key issue was the consumption of alcohol and the use of firearms.
Mr Daisley said there needs to be a culture where hunters feel okay to speak up if they see something untoward.
"Hunters by and large are a very responsible community.
"Unfortunately, the excitement of opening weekend brings a certain boys' weekend feel to it with some groups.
"We'd like to encourage hunters to speak up if they see drinking and firearms use.
"If nothing is said then we collectively accept this as an acceptable behaviour, which it isn't. Leave shots with the lads until after the shoot."
The NZ Mountain Safety Council has created a range of resources designed for easy consumption online in an attempt to reach newer audiences, said Mr Daisley.
"We've worked on several initiatives this year, including the six-part video series with Big Game Hunting New Zealand to explain and make relevant the various components of this code.
"These are available online via both the MSC and BGH Facebook pages, as well as the respective YouTube channels."
Refreshing yourself on the basics is something all hunters should be encouraging among themselves, Mr Daisley said.
"We'd love to see these videos shared and promoted through the hunting communities themselves.
"So far we've had hundreds of thousands of views, which is great," he said.
