The Mystics lost their final four regular season games on the trot before getting well beaten 63-57 by their cross-town rivals - the Stars - in the elimination final.
Winikerei said they performed an in-depth review of the situation during the off-season and have learned a lot from it.
“We were able to apply that quite quickly and work our game plan so that it is similar yet goes beyond where we’ve played before.
“We’ve got a roster in which every player is capable of taking the court so it was stretching our game style to include everybody more often.”
Winikerei said Nweke is a difficult player to replace.
“She’s got a unique skill set that’s different to every other player in New Zealand and in the world.
“Our strategy will be to play a different style of netball in moments that she isn’t able to play.”
Winikerei said this new style will adjust how the midcourt works with the inner circle.
“But also the contribution of the seven players across the team, and that the load is equally spread in any given moment. It’s not to say this isn’t the game plan when Grace is on the court. We’ve worked hard to blend the two styles together no matter who’s on the court.”
Nweke, captain Sulu Fitzpatrick, Phoenix Karaka and Peta Toeava were away with the Silver Ferns squad during the Quad Nations in January.
Winikerei said their preseason absence became an opportunity for other players to gel together in the ANZ Premiership build-up.
