Recent research - NZTA
One of the objectives of these pages is to promulgate and publicise research to encourage wider adoption of research recommendations and the application of findings. This page provides a summary of recent NZTA research reports and other presentations. For a list of currently active research projects and approved projects not yet commissioned, click here.
The RCA Forum is also supporting or steering research through its Research and Guidelines Steering Group and working groups. As well as long-established working groups, such as the National Stock Effluent Working Group or the Stormwater Group, new working groups are being established as issues arise. More >>
The NZTA-NZIHT 12th Annual Conference - Building and maintaining highways for the future - produced a substantial library of presentations on a very wide range of topics addressing the conference theme and relying in many cases on the most recent research available in 2011. The list of presentations is available here.
