- National Public Transport Strategy
- Time for a national regional passenger rail network
- Time for a national public transport network
- Lets Connect Communities
- Future of New Zealand's land transport and communities
- Can semi rural towns and small rural communities have public transport?

If you support a national public transport network concept, have your say or become proactive by getting involved in local better public transport campaign groups.
