Susan Wood could have done her homework a bit better. No mention of the fact that all meat bomb dropping stops when Eagle call taxing and when 30miles out. (Is it 30? - i stand corrected there). Also no mention of the fact that the jump planes don;t just drop at their own free will, they need a clearance to do so.
I am regulary in and out of Taupo and have never had a problem. I have to say though the unicom service there is definately useless though.
