Trumps immigration executive order & green card holders with misdemeanor conviction

Back in 2008 I was charged with a misdemeanor with buying alcohol for someone under age 21. I paid a $500 penalty. I received my green card in 2011. The conviction was documentes my green card application so it wasn't omitted off of the application or anything like that. I am wishing to travel back home to New Zealand for a vacation next month but worried if any of the executive order will affect me returning? Is it ok for me to travel with being in the country legally as a permanat resident with being a citizen and having a New Zealand passport. I have traveled between the U.S and New Zealand many times since receiving my permanent residence
