In the United States, each state has completely different laws. Australia and New Zealand are different in that they have had separation divorce. In Australia, the only ground is a one-year separation, which has been in place since 1967. We did a comparative study as part of the research and really struggled to find Australian and New Zealand respondents, academics or experts, because there is just no research on the grounds for divorce. It is just not an issue because the reform took place so long ago and that is just how things are.
