I loaded up the NZ version as well and its like a new tablet. Very smooth and battery life is much better.I just bought the Samsung Galaxy Tab S2 9.7 T810 and installed the NZ rom and it's running great so far. Install TWRP with ODIN and backup my original rom and install the NZ rom with ODIN and reinstall TWRP back on it and rooted it in TWRP recovery. ODIN just makes everything so damn easy. Did not need to install the Samsung USB drivers on Windows 10. The only thing I see missing is "Eastern Standard TIme" but I just use "New York" and that pretty much turn it to "Eastern Daylight Time".
