NZR commissioned the "Respect and Responsibility Review" in 2016, after a series of scandals mainly involving players.

The review, which cost more than NZD$150,000 (£82,600/$109,000/€90,500), investigated 36 cases of misconduct in the last four years.

Overall, 100 recommendations have been made to NZR with six "key changes" to be implemented over the next two years.

Former All Blacks Keven Mealamu and Michael Jones, plus Olympic kayaker Lisa Carrington and others were on the panel led by Kathryn Beck, President of the New Zealand Law Society.

The areas to be addressed include: "inclusive leadership", "developing people", "nurturing wellbeing", "gender equity", "proactive engagement" and "being accountable and independent".

The most prominent issues centred around the impact and consumption of alcohol, attitudes towards women and a sense of entitlement in some players.

Of the 36 incidents, 33 involved players with four individuals found to be repeat offenders but no identities were revealed.

Findings revealed a failure to attend meetings, judicial hearings or assemble with the team, a lack of compliance with agreed programmes, including rehabilitation, and drunk behaviour.

Inappropriate sexual behaviour towards others was also highlighted as well as violence towards others, including team members and coaches.

There were also instances involving alcohol and drugs as well as a homophobic slur that was overheard by the public and complained about.

All Blacks scrum-half Aaron Smith was found guilty of misconduct last year after an incident at Christchurch Airport.

The Chiefs, a provincial team based in Hamilton, were also involved in a scandal after a woman alleged she was sexually assaulted by players after being hired to strip at their end-of-year party.

No players were charged by the police, but they were handed formal warnings by NZR.

"Undertaking any significant culture change in any organisation is complex and takes time", said NZR chairman Brent Impey.

"The NZR board is committed to setting a long-term programme for action that will deliver a number of activities in the short, medium and long-term.

"Rugby has long been held up as one of the unique vehicles for New Zealanders to feel connected to each other, to be inspired, and be great members of their communities.

"We want to play our part in those opportunities and ensure rugby plays a positive role in our society."
