Christchurch foreknowledge?

Interesting thread questioning the proposition, put forth by Fletcher Prouty and popularized in the ‘JFK’ movie, that details of the Kennedy assassination were published in a Christchurch, New Zealand newspaper prior to the time of the assassination (the issue is fully explored here).  There is no obvious reason to spread the story early, and the danger of pre-reporting is the obvious one that the assassination may not have gone as planned, leading to some serious questions to answer.
