I searched pretty thoroughly for Tzezguerra's nen type, it's stated nowhere and he's treated as "unknown" by both games.

Goreinu's nen type was confirmed manipulation and is never stated at any point to be anything but manipulation - my speculation is that people took his line about "doing the same thing" as Razor (re: using nen constructs as teammates) as an indication that they had the same nen type, which is not the case.
