Find a specific term but exclude instances where that term is followed by a specific word.

Hiya, 

I'm trying to search a large document for all instances where "NZ ultimate" appears on it's own but I don't want to find instances where "NZ Ultimate Diesel" appears. ie. I want to find all instances of "NZ ultimate" but NOT when it is followed by the word "Diesel". Can I format a search for this? How if so?

I think you'll have to use a script to do it. The results can be highlighted, for example.
