Thank you all so very much. Wonderful advice (and what I thought). He will be doing a bachelors as he just started university last January in the teaching program in Stockholm so he's hoping to transfer. Right now he took the IETLS and did very well on all parts except the writing where got a 6.5 instead of a 7 which is required for admittance into the teaching program. We don't know if there are any exceptions to allow him in and take the test at a later point, but he is going to apply with a letter and ask. We did see Massey has an extramural program for teaching so that will be the first choice, otherwise he'll aim for a bachelor's focusing on mathematics and try transfer later to the teaching program.
Thanks for the suggestion about having an apartment at Massey while he's at school. If we had an idea how many days he'd be at school and if it was only a few days a week we would consider it, but we don't know about doing that if it's everyday. It's only me working so he can study, so money wise we might not be able to afford 2 apartments.
The option about Waikatu is super with the intensive blocks. That would be a good solution. So we will look into that too as a second choice.
The reason we are living on the base is because they are providing a cheap apartment for us. We figured living in the middle wouldn't be a good solution since we'll both then have long distances to travel & the cost of two cars on just my teaching salary.
I so very much appreciate all the ideas. They were very helpful and I might pm you TJH for advice since you seem to be familiar with the school, your wife currently there
