With the Tactix struggling to put together a competitive roster, ANZ Championship general manager Anthony Everard said the league felt compelled to help out.
"We are satisfied that the Tactix have explored all options in their endeavours to contract players, and recognise that given the unprecedented circumstances they are experiencing, there is a role for the league to play via the provision of this support."
While they empathise with the difficulties the Tactix face, several franchises are said to be uncomfortable with the league making exceptions, saying it creates a precedent.
However New Zealand Netball Players Association manager Tim Lythe is confident the league's actions have not created any loopholes.
"It was quite an extraordinary event that caused the disruption and I don't think any team can argue they face similar challenges," said Lythe.
New Tactix coach Leigh Gibbs said it was a relief to get the green light to sign a second import. It is believed the Canterbury side have been in talks with three potential imports, but Gibbs denied they had a player lined up.
It is believed English defender Ama Agbeze is the frontrunner for the second spot given her previous experience in the league, with young England stars Stacey Francis and Serena Guthrie the other options.
