Race organisers announced on Friday that they have had to postpone their inaugural event because of construction issues at the venue.
In a statement it said that some of the problems related to the development of facilities at the Hudson Riverfront venue, which included the pits and paddock.
Although the delay has prompted doubts about the event ever taking place, Ecclestone has made it clear that he will do everything he can to ensure that the grand prix happens.
"I remain totally committed to the Port Imperial race and its unique location and attributes, and we will continue to work closely together to realise our dream in 2014," he said.
Race promoter Leo Hindery Jr said the decision to delay had come about because his staff wanted to ensure that when the race went ahead it was put on to the highest standard.
"We are going to be racing at Port Imperial, unfortunately just not as soon as we hoped and expected," he explained.
"We promised Governor Christie, the towns, the sport and its international fans the best possible experience, and unfortunately we need additional time to ensure that happens.
"We remain 100 per cent committed to the Grand Prix of America at Port Imperial, and the race could have no better partner and friend than the CEO of Formula 1, Bernie Ecclestone. We benefit greatly from his experience and counsel and from his support."
The loss of the New Jersey race means that there will be just 19 races on next year's calendar, with Ecclestone telling various media sources on Friday that he had no plans to find a replacement event.
