I have downloaded the corresponding package's from WOAI.  At both airports there is traffic in the air around the airport but no landings or ground traffic

 

I use VOX atc that does a good job every where else with loads of AI.

 

Any one have any advice on how to get traffic to these airports as I have bought Pacific simulations corresponding payware but there is still no traffic even when in default mode

Try to disable ""Aircraft cast shadows on the ground" from FSX settings if you haven't done it already, many addonI airports seem to make non FSX native AI models to disappear when that setting enabled. 

Yeah, that's already disabled
