The first is a Virgin Australia Airlines [NZ] Boeing 737-8FE, ZK-PBG. This livery is getting much rarer as the aircraft are progressively repainted into the current Virgin Australia livery. Note in particular the very very faded fuselage top.
The second is a Jetstar-registered Airbus A320-232, VH-VFD. Last we have a Marlborough Helicopters Bell 206B, ZK-HJI. This aircraft was transporting a One News crew to and from a bush fire at Port Underwood near Picton [click here for an early news report from stuff.co.nz]. I guess you'll see a report on the TV tonight, but you saw it here first [at the least the interesting part... the helicopter!] :-).
