The latest Austrailan tour backed by controversial promoter Andrew McManus has been postponed just days before it was set to kick off.

McManus, who last August pleaded guilty to attempting to pervert the course of justice in regards to a suitcase containing over $700,000 in cash found in a Sydney hotel in 2011, confirmed the postponement of Raggamuffin Music Festival in a statement over the weekend.

"Ticket sales for the festival have slowed in recent weeks and appear to have been impacted by various factors including an announcement that train services will now not be available on the event date due to track work being done," McManus said. 

"Patron comfort, security and the importance of protecting local suppliers is paramount and was at the forefront of this decision. With these factors in mind we have no option but to postpone Raggamuffin X to November 2017.

"This will give us time to work through campaigns and the overall success of the project both in New Zealand and for associated concerts in Australia."

The promoter added that all artists on the bill, which featured the likes of Shaggy, Six60 and The Wailers, have given assurance that they will be free to return in November.

"We sincerely apologise for inconveniences caused by this decision," McManus continued.

"I can assure all that every aspect has been reviewed and this decision has not been made lightly."

Ticket purchasers can retain their tickets and await further information on a new date and venue. Refunds are available through point of purchase.
