TMR put this up on their Facebook asking who has to give way, but that's too easy. A much more complicated question is: what does the law say around indicating?
I've seen people say only blue must indicate, others say both must indicate, and yet others say neither must indicate. Which is correct?
Yup, that part is easy enough. The part in doubt is who has to indicate in this scenario. I contend section 45(2) and (3) both apply, so both drivers must indicate (blue indicate right, orange indicate left). Others have made cases for only blue, or for neither.

Only blue indicates, because they are the only one making a physical lateral movement with respect to their lane. The bike keeps straight with respect to their lane so no need to indicate.
