Harry needs travel insurance to cover Hydrocephalus and Epilepsy

Kia Ora Andrew, My name is Tom and we are trying to find travel insurance cover for our son who also has Hydrocephalus. I was just wondering if you would be willing to share the name of the company you found who was willing to cover it? I know this post is a little old but we are hitting a bit of a brick wall here. Cheers, Tom
