I had taken myself trespass as I am playing reguraly in skycity casino auckland. I want to go back to casino but can thy allow me to get in.as thy told me I can't allow for 1 year.

As it is private property they can allow whoever they like to be a patron and use their facilities.
From you rather jumbled post it would appear you access to this establishment has been suspended for a year.
You could try writing a letter of apology to the General Manager/Owner and ask them to reconsider their discussion.
