Last week, the city began repairs to the rink's valves and concrete slab after leaks were found, the agency said in a statement.
They worked on identifying and fixing the source of the leaks. The repairs were successful and allowed the refrigeration system to start making ice again, according to the statement.
Lasker Rink is operated by the Trump Organization, but the Parks Department is responsible for repairs.
The rink, which is often used for hockey and skating practices, was expected to be closed for most of the winter, according to the New York Times.
“We are thrilled to welcome back Lasker Rink for this winter season,” said NYC Parks Commissioner Mitchell Silver.
“The rink is a beloved neighborhood destination during the winter months, and it offers a fun and exciting way to stay active and enjoy the cold weather. I applaud all of the NYC Parks employees who worked diligently to make the needed repairs," he said.
Hockey games, practices and skating lessons will resume on Dec. 1.
