Kalezic isn't thinking yet about using the January transfer window to boost his squad, but says players will have to prove their commitment if they want to hold onto their places.
"Only players who are going to give 100 per cent effort for this club, those players are going to play. Players who cannot give 100 per cent, they will not play for the Phoenix."
Sunday's game also included a new twist with the surprise absence of Brazilian midfielder Gui Finkler from the matchday squad.
Finkler was stood down following a petulant reaction to his 55th-minute substitution in Wellington's 4-1 loss to Central Coast Mariners nine days ago.
"For disciplinary reasons, he is not here," Kalezic said.
"Gui, after the change, he leaves the field, he leaves also the changing room and he leaves the stadium.
"He didn't wait for his teammates, and made a choice for himself."
Kalezic doesn't believe Finkler's reaction is indicative of any wider problems in his squad.
"I don't have issues with players at all - we work in a really good atmosphere with each other, and the players are really happy on the training field," he said.
"Everybody has to realise, we are here for the Phoenix. I am not here for myself - I am here for the club.
"The club is in the first place, and not me."
