Northern Mystics chief executive Julie Paterson said that while teams were granted an extension this year to assemble their line-ups, they still had an exceptionally limited time frame to secure signatures.
"It has been a really challenging exercise. The Silver Ferns programme added the greatest degree of difficulty, because their season was so long and intense this year and we are not allowed to contact them in camp, it was hard to get any continuity in our communication," she said.
Teams must submit at least 10 contracted players to the ANZ Championship office today and confirm their full line-ups by the beginning of next week.
Given that the Silver Ferns only wrapped up their test programme on Thursday, it is unlikely any will spring a surprise move at this late stage.
The key movements have been signposted for quite some time.
The Pulse look to be the biggest benefactors in the off-season recruitment race, with Robyn Broughton luring back two former Steel alumni, Liana Leota and Donna Wilkins.
However, it is believed the Pulse are having difficulty finalising Wilkins' contract, with the Wellington-based franchise struggling to fit what they originally offered Wilkins under the new salary cap rules.
Wilkins has apparently sent her contract back to the Pulse several times.
Third-party payments are still permitted with the new cap, but it must be a genuine contract for services and declared at the same time as the retainer contract.
