So I'm receiving data over UART from another AVR. However I'm doing other stuff so dont want to have constantly keep polling the UART. I know there are interrupts but i can only see one for receive complete. Which I assume still requires me to poll to the complete the transfer.

Why would you need to poll to initiate a transfer? Anyway, there are interrupts for transmission completion as well. I am not very into AVR, but these can be called "TX empty" or "FIFO empty" or FIFO threshold" or similar.

There are interrupt vectors for both RXC and TXC (RX and TX complete) on AVRs. You should never have to poll for these unless you want to.
AVRFreaks has a nice post on this, and so does the manufacturer.
