I posted and then deleted because I was getting into stuff that I don't think the OP meant to get into, but you can find some GPA requirement stuff on at least some of the NPHC groups. They don't necessarily say what it takes to stay in good standing, but you can find requirements to rush/intake.

One thing to keep in mind is the relatively small chapter size of some NPHC groups compared to NPC or NIC groups. If you have a small chapter, it might make more sense not to worry that much about average GPA since one or two people can affect it so much.
