NZ Task Group Black exercise patch

[Quicksilver]

Following information received from NZ badge collector and author. He sayd he saw a New Zealand soldier wearing a subdued MCU patch with the fist and lightening bolts. He also says he is also looking for an example of the Task Group Black exercise patch per attachment. Most recently worn by a contingent in an Australian Exercise Hamel. The design is rampant dragon of 1 NZ Army Tank Brigade (WW2)!
Perhaps NZ patch collectors can advise more about the two patches. The first one with the fist and lightning bolts sounds like the old RAF trade patch and I wonder if it is in fact a RNZAF communications patch.
