Good that they are being upgraded, but in reality it is yet another poor decision by the government. The RNZAF C-130 are some of the best maintained and well looked after C-130 in the world, this however does not make them invulnerable to age related issues! They are tired aircraft and the NZDF needs a more capable aircraft now that it has LAV-III APC's. The C-130H that the RNZAF operates can barely take a LAV-III and can't fly very far with one. The RNZAF either needs to order C-130J or A400. It would be nice if they got C-17 but in reality this is too much aircraft for New Zealand - too expensive and not as suited to the RNZAF needs as a C-130 sized aircraft. Perhaps New Zealand could purchase 1x C-17 and attach it to the RAAF fleet under an agreement with Australia.. that could be mutually benefitial to both countries.
The problem with the C-130H is that the engines are old, use more fuel than newer engines, don't have as much power thus the aircraft is not as capable. The airframes are also tired. It may be possible to re-engine the C-130H with -J engines but at the end of the day it would be a waste of money when for a little more brand new aircraft could be purchased.

Quoting Zkpilot (Reply 2): The problem with the C-130H is that the engines are old, use more fuel than newer engines, don't have as much power thus the aircraft is not as capable.
Only true comment there is that the engines are old and use more fuel.
The C-130H's Allison T56-A-15 has 4,591 SHP and is limited to a max torque of 19,600 in/lbs. The C-130J's Rolls-Royce AE2100D3 is also 4,591 SHP and limited to 19,600 in/lbs torque. The torque limit is imposed by airframe limitations.
The only reason the Rolls-Royce AE2100D3 makes the C-130J more capable is its reduced fuel consumption and ability to provide max power to a higher altitude.
