While the defamation proceedings in chief are not due to take place until later this year, lawyers for both parties are due to appear in the High Court at Auckland this month where two applications are expected to be advanced.
Hotchin and Watson are expected to apply for the proceedings to be heard by a judge alone without a jury, a move which Sheppard will oppose.
The Hanover pair also want a review of a decision from the High Court last year relating to whether pleaded instances of Hotchin and Watson's alleged past "misconduct" could form part of Sheppard's defence.
These instances include Watson being censured in 1998 by the Securities Commission for buying shares in McCollam Print while negotiating its takeover by an entity related to him.
They also include claims Hotchin breached Securities Commission guidelines in 1999 on insider trading in relation to the sale and purchase of shares of a company called Pacific Retail Group.
In citing these alleged "misconducts" Sheppard is seeking to show Hotchin and Watson were not persons of "particularly good reputation" in relevant respects and that this should be taken into account.
Hotchin and Watson attempted to have the "particulars of misconduct" struck out by the High Court, but Associate Judge Jeremy Doogue dismissed the application last October.
This story has been changed from an earlier version, which said the Shareholders' Association settlement was "worth hundreds of thousands of dollars". This has now been corrected to say "a six-figure sum."
