The treatment of the teams in the national championship illustrated how women had a low priority in the sport, he said.
''Women's rugby gets the raw end of the stick in terms of travel, '' Gray told the Otago Daily Times.
This was demonstrated by the Otago team's travel arrangements last weekend when it played Counties-Manukau.
''We reached our destination at 12.30am in the morning and had to get up at 7am and play the game at 11.30am.
''That's a big ask for any team and especially at this level. It's something that needs to be looked at before next year.''
Otago captain Halie Hurring agreed.
''It was tough on the bodies and was not good preparation for the girls,'' Hurring said.
''We would like to see that change. Other provincial unions are complaining, as well. It is too tough on the girls to travel like this week in and week out.''
Gray would also like semifinals to be introduced to the women's national championship.
''We are at least worthy of a semifinal,'' Gray said.
''If you lose your first two games in this competition, you're out. There is no incentive to play any more.
''The New Zealand Rugby Union will need to look at that and try to dangle a bigger carrot in front of the teams to generate a lot more interest and enthusiasm for those wanting to join the 15-man game.''
Otago and Manawatu will be playing for third spot at the North Ground today.
Otago started the representative season in style and won its first four games, the highlight being beating Auckland for the first time in Auckland.
But the Spirit lost the JJ Stewart Trophy to Canterbury and was beaten by Counties-Manukau last weekend.
It has still been a good season for a novice Otago team that had lost three of its Black Ferns from last year.
''We are a bunch of no-names. I think that is why we have done so well,'' Hurring said.
''We have stuck together and performed, from the props to the wings ... I did not know what to expect from a bunch of new girls. Everyone has made a mark and stepped up.
''I hope the Black Ferns selectors see that, as well.''
