Have to agree with Danyl's post on this. ACT is now little more than a scam that National is running to hoover up the votes of those to its right. There are still a few genuine ACT candidates at the upper levels of ACT's list, but they'll be dependent for their seats in Parliament on John Banks, a staunch National man and natural conservative opposed to most of what ACT supposedly stands for.
It's kind of a shame, really. I like the idea of a classical liberal party represented in Parliament to act as a counterweight against all the other parties' tendency to treat the citizenry as recalcitrant children who must be made to behave the way their rulers feel is appropriate. It's just too bad that we don't have one - under Hide, ACT went in mainly for populist rabble-rousing (eg the get-tough-on-crime stuff, or the hypocritical perk-busting), and most of the people representing ACT in Parliament have turned out to be fruitcakes of one kind or another. Now they're just a front for National to keep the few remaining ACT supporters from disappearing under the threshold. Not a pleasant end for them.
