Spacegass has a good steel design module. Though I have never seen a copy of this program online. Though it is cheap if you are considering buying it and relatively powerful as a general frame analysis tool.
Etabs and SAP2000 in the latest versions have inbuilt NZ and AU seismic codes for deriving response spectrums cases.
Etabs also can design concrete to NZS3101:1995, note this isn't the latest revision of the code though.
PCAcolumn can be adapted to use NZ (and presumably AU) design parameters for the design and checking of RC columns and beams as ACI318 is very similar except for some of the strength reduction factors and other parameters.
