Good question: there's so much anti and pro opinions on the LAV's (probably as part of that tracked v wheeled arguement, see elsewhere in DT's archives and elsewhere on other forums etc), I find it hard to seperate facts from opinions and have seen what appears to be biased or hysterical BS.
However for an interesting link nonetheless on the anti-LAV side, see

I suppose the NZ Hilux is a good general purpose vehicle suited to the terrain where we operate (after all the Jihadist's and Taliban have used Hilux's, obviously they do the job
), but I would like to see something additional be that Armoured LOV's or LAV's or new Bushmasters etc there in a support role where possible (unfortunately the NZ Army M113's were scrapped a couple of years ago). I would (again) say NZ needs a tracked vehicle capable of transport in a C130 (second hand upgraded M113's?) to compliement the LAV3's - I believe there is a place for the LAV3 in the NZ Orbat - but that is such a highly politically charged issue as you most likely know - that would take a change of Govt to have the guts to sort out.
Note: I've never heard of the Aussies complaining of their ASLAV's (maybe they have but I haven't seen it) but at least they have tracked M113's and ASLAV's as well as the Bushmaster for various tasks (admittedly in different roles though. See Aussie Army thread in DT for more info etc).
