No real ideas, unfortunately.
Umm, try squeezing into press conferences. Try contacting people you've interviewed before and asking for their help. Say, you want to talk to the minister for community development, and twelve months ago you interviewed the minister for planning and infrastructure. Ring the P&I minister and see if they can arrange a meeting with the CD minister.
Of course if you ripped into the P&I minister this is probably not going to work.
