"New Zealand lacks a national unifying myth"

"New Zealand lacks a national unifying myth that embodies the shared views of the country’s history and future. The loss of a common national story is central to many of News Zealand’s problems. Myths explain our history, chart a path to the future and help bind the country together.
    "Richard Slotkin, who has written extensively about the various mythologies underpinning the United States experience, suggests that ‘myths are the stories – true, untrue, half-true – that ... provide an otherwise loosely affiliated people with models of patriotic action.’ A more formal dictionary definition suggests that myths may be popular traditions embodying core social values* ...
    "There have been a number of what may be described as archetypal experiences in New Zealand history that could approach a 'mythological' status that reflect the embodiment of some of the values that underpin the national identity. ANZAC immediately comes to mind. Wartime activity and service brings a people together often because national survival is at stake.
    "Then there is the 'man alone' myth that underpins much of Jock Phillips writing, along with the Kiwi do-it-yourself 'number 8 wire' approach to problem solving. Sport tends to be a unifier but primarily a hysterical support for the All Blacks which rapidly diminishes if the team does anything but win. Sport is meant to demonstrate resilience in the fact of adversity but not, it would seem, on the part of the fans.
    "Historians are well positioned to invent and develop new national stories. ... But historians have not taken on the task of devising a coherent national mythology that can bring unity to a fractured nation. Instead, students are being taught radically different versions of the nation’s past. All this reflects not simply divergent opinions on specific issues, but disagreements about the fundamental character of our institutions and the purposes of our nation.
    "One myth which did possess a unifying feature but which has been badly eroded is the position of the Treaty of Waitangi. The treaty established a foundation for equal citizenship, one people with equal recognition under the law.
    "Hobson at the signing of the Treaty is reputed to have said 'He iwi tahi tatou – 'we are now one people.' ... The problem is that in many respects myths [like this one] contain a great deal of invention and not a lot of evidence. But Hobson’s Pledge, whether it was said or not, provides a solid background for a national identity and the foundation for a common purpose. We should be one people. We should acknowledge our differences but our shared objective should be a unity of purpose. And with that unity of purpose we can become ... a country with well-educated people, who enjoy the lifestyle their unique setting offers and the good health that goes with that ..." 

~ Thomas Cranmer from his post 'A Common Purpose and a National Mythology'

* Myths are not a lie, explains mythologist Joseph Campbell, and to call them that is a misunderstanding — 

"a very strong and narrow opinion of what a myth 'is.' Someone who, perhaps, has only been exposed to the negative use of the term as a phrase for something that is seen as a 'mistruth.' Something told with the intent to deceive, or from the vantage point of a naive or uneducated mind. For many, calling something a 'myth' is to associate it with a profound deception: a feeble or unsophisticated attempt to explain material reality before the advent of the scientific age. Some see the term as an equivalent to the more modern 'fake news.' 

"The contemporary conception of myth as falsehood has led people to think of myths as fairytales (another complex story structure that is often dismissed as containing much less essential truth than they actually do).
"But for Campbell, myth presents a version of the truth that is far more essential than that which can be gleaned from almanacs, censuses, and encyclopaedias, whose 'facts' are dependent on the experience of the field of time and are often outdated as soon as they are published."

Writer Robert A. Johnson sums it up, saying "Myths are a special kind of literature not written or created by a single individual, but produced by the imagination and experience of an entire age and culture, and can be seen as the distillation of the dreams and experiences of a whole culture." 

So neither unimportant nor trivial. And certainly not a lie.
