The work "Landfall in Unknown Seas" is still available on CD according to the SOUNZ site; Landfall in Unknown Seas (http://sounz.org.nz/works/availability/12111#recordings). It's not really neglected in NZ, I've played it in an orchestra there at least one time that I can remember, and also the Third Symphony that I prefer over the first two for its conciseness.
