Although there is no genre of music that has been officially dubbed 'nu rock', many see nu rock as another name for post-grunge for sounding similar to nu metal without the metal feel and the elements of hip-hop. Although post-grunge isn't commonly known as nu rock, many believe that if you had to call any kind of music 'nu rock', it would have to be post-grunge more than anything.
"Who's your favorite nu rock band?"
"Nu rock? You mean nu metal?"
"No, nu rock. You might know it as 'post-grunge'."
"Oh! In that case, my favorite 'nu rock' band would have to be Creed."
