The How to Look Good Naked star was due to host the Westfield Style Tour through Australia and New Zealand during April.
A series of free live shows were scheduled for the three Westfield centres in Auckland.
But Wan has been hospitalised with a bad back and is looking to reschedule the Australian tour for later in the year.
He has kept fans updated with his health worries on Twitter, posting today: `Not a great day with my back... Love would be greatly appreciated!'
Wan also tweeted that he is on morphine and faces back surgery.
