Up to 120,000 workers are set to stage a fresh round of strikes from Thursday unless progress is made.
Mr Ward, before entering the latest discussions, said the dispute was "fundamentally" about jobs and workers' terms and conditions.
He said the issue of the Royal Mail's pension deficit - thought to total about £10 billion - needed to be resolved urgently.
"There's no prospect of us building a successful future for the Royal Mail and for the workforce unless the Government actually deal with that issue," he said.
Do you think it is right that postal workers are set to go on strike? Will the strike affect you? Do you work for Royal Mail?
