US visa with NZ passport

I'm holding a New Zealand passport, i checked online it said NZ has joined the visa waiver program. I got my passport on 31/10/05 and I know to be eligible for the VWP, my passport needs to hv an integrated chip or the digital photo, how could i know is my passport has either of the requirement?

If my passport has either of the requirement, is that mean i do not need to apply a visitor visa (i'm going to hv a conference from late-may for about a week) or i need to apply an electronic one just like the one for australia?

many thx!
