Thread: Jet boating into Whanganui NP

A mate has bought a jet boat, and we're thinking of doing a trip into Whanganui NP at some point chasing fallow. My understanding is that they're not found throughout the park, with large tracts being only pig/goat country. Is anyone able to shed light on which areas do/do not hold fallow, that are accessible by boat? Not after spot X's, just general areas would be much appreciated.
