The Saints have signed on with current VFL affiliate Sandringham for another year, which extends their agreement to an eighth season.
They had planned to play a standalone team out of Moorabbin when their previous deal with the Zebras finished at the end of 2015.
But the Moorabbin redevelopment is not expected to be complete before the start of the 2016 season, which means the Saints will align with the Zebras until at least the end of that season.
"St Kilda and Sandringham have had a long and rewarding history together and we are extremely pleased to have the Zebras as our VFL affiliate until the end of 2016," Saints head of football Chris Pelchen said.
"While our intention remains to field a standalone VFL team based at Moorabbin, we see the recently revitalised alignment with Sandringham as providing mutual benefits for both clubs.
"The redevelopment project at Moorabbin will not be completed in time for the 2016 season, so this new agreement will provide St Kilda and Sandringham sufficient opportunity to prepare for the transition into standalone clubs."
The announcement comes after Sandringham secured a position in the VFL finals with a 20-point win over Werribee on Saturday.
The Zebras are coached by St Kilda Academy manager Simon McPhee.
Both St Kilda and Sandringham believe there are positives from the extension of the alignment, which wasn't expected 12 months ago.
"We are so pleased the Saints and Zebras will extend our partnership and continue to provide a career path for talented footballers in a program focused on developing players in a successful team environment," Sandringham general manager John Mennie said.
"St Kilda has been tremendously supportive of Sandringham and there has been wonderful camaraderie in a playing group that has been made up of St Kilda and Sandringham listed players."
The Zebras’ home ground and St Kilda’s best and fairest award are both named after the late Trevor Barker, who played 230 games for the Saints.
Barker also coached Sandringham to premierships in 1992 and 1994.
