I am changing from a gas cooker to an electric cooker, can any one tell me the size of the fuse I will need as I have a spare 45amp in the consumer box , the cookers rated at 11.2 kw with a cable run of 6mts from consumer box

It works out at 49Amps,
but applying diversity, you should get away with 45A.

the oddds of every single element being on at the same time and for long enough to damage the cable / blow the fuse is slight..
each element has a thermostat and cycles on and off once up to temperature..

I see where you coming from, but the OP has 45A fuse he can use it.
If the OP decides to change to a different rating, then we start talking about part p!
So the general consensus is its ok to use the 45amp fuse
Aye, NOT!
No so fast.
Nobody has asked what the csa of the cable is.
He may have a 45A fuse in the board, but what if the cable is only 6mm and run through the roof insulation?
Yes, but you never even considered the size of the cable before saying "aye".
The fuse is there to protect the cable from over current.

to apply diversity of a cooker circuit the age old formula may be used unless in your engineering judgement other factors effect this.
