"We've organised trainings for Wednesday and Thursday, in anticipation of a ruling going in our favour," Morley said.
He says he has evidence which shows certain Havelock North players were not registered until 11.37pm on the Monday following his team's loss to Havelock North.
Co-club captain of the Havelock North club Gary Revell pointed out the lack of registrations were the result of a New Zealand Rugby Football Union data base problem.
"This isn't just Havelock North, it's a nationwide issue. Historically, Havelock North has been one of the leading clubs when it comes to registering junior and senior club players," Revell said.
Taradale coach Blair Cross said his team would be gutted if they had to give up their semifinal berth. "But I don't think it will come to that, in all honesty. If Havelock North played unregistered players in that game, they must have played unregistered players all season.
"This is an administrative issue and I believe the top four teams sorted themselves out on the field. I'll be shocked if anything changes to the order and we're training tomorrow and Thursday as planned," Cross said.
Union chairman Brendan Mahony said he is planning to make an announcement by 5pm today. "At our meeting we will consider a recommendation from our rugby directors before coming up with a way forward on this matter."
Club competitions manager Gary Macdonald sent out the weekend draw yesterday and there was no mention of the protest. The semifinal draw had top qualifiers Napier Technical hosting fourth qualifiers Taradale at Whitmore Park, and second qualifiers Havelock North hosting Napier Old Boys Marist at Anderson Park.
