One thing which really seems to cement things where I live. There a monthly new music presentation night. A bunch of musicians (chip and other electronic genres) get together in a cafe with a sound system, listen to a tune an artist is working on, make a few comments, listen to another tune, make a few more comments. People play tunes off their mp3 players rather than bringing a live rig. Really nice night.
Start playing music at events which aren't chip music events. If there are raves, parties, open mics, whatevers in your city, go play them.
Save money, cash always seems to be a major factor in getting regular nights started. Also don't expect them to succeed right away, scenes build slowly. Also, it could be used to fly in an international from aus/japan/west coast us/indonesia.
Start a podcast, showcase new NZ chip music, make a bunch of noise about what you are doing.
Buy extra gear, get a nice backlit DMG or 3 with flashcarts with LSDJ or nanoloop, lend them out to people who might be curious so they can fuck about WHEN they are curious not after 5 weeks fucking about looking for hardware and loosing interest.
Train a VJ or learn to do it yourself, VJs can be hard to find.
Get on local/college radio, tell them you have a night.
Bug your local newspaper to publicise what you are doing.
