Thanks for all your advice!
We haven't driven the car anymore since my last posting. Currently we are moving house and the works on the Honda Jazz have been postponed.
I managed to go to a Honda dealer and bought 8 liters of the Honda CVT fluid for $204.00.
I will drive the car for a 100 km with the new CVT fluid and then change it again with fresh CVT fluid.
Hopefully it will sort out our problem and I will keep you updated.
Cheers,

Luc
