The mecanical conversion/FTE swap populatity in NZ/OZ is driven by stuff previously mentioned above plus supply factors.
The 1HDFT only ever came new in 80s and for a comparatively short period. Toyota didn't make that many of them and the tend to stay in the trucks they were born into, and they seem to be mostly in JDM trucks which NZ and Oz have been importing for ages (triggered by govt deregulation of the manufacturing industry here).
Conversely 1HDFTEs came in 100 series and 70 series trucks of which there are heaps of in OZ.
All this means that if you are looking to upgrade from a 1HDT or 1HZ then chances are you wont find a 1HDFT, but 1HDFTEs are easier to come by. I've been keeping an eye out for a 1HDFT for several years, and I've seen 1 pop up in that time, but have seen several 1HDFTEs.
Also remember that rebuilds are really expensive on these engines, meaning that a few grand to sort the really basic wiring or swap a manual pump for a 1HDFTE is pretty good value.
