The ORSNZ conference rotates around the NZ universities in the sequence Auckland (2002), Hamilton (2003), Wellington (2004) and Christchurch (2005). (Council resolution July 2001). This sequence was broken in 2004 for a joint conference, and to allow our 2005 40th year celebration to occur in our birthplace, Wellington (home of the old DSIR). The 2007 conference was not held in Hamilton at their request, but instead in Auckland.
