Another plug for the hollyford, one of the most amazing places in the world. Milford is a must see and the river runs are no different, definitely worth the drive. when I took my kayak out in the sound I saw bottlenose dolphins, seals, and penguins. Marian and falls creek runs are also phenomenal, there is also monkey creek which i didnt do, but heard there is a lot of mank and portaging. There is nothing like paddling in a rain forest and looking up to see snow capped mountains. There is also a short class 4 section at the end of the dirt road worth checking out, especially if the flow is high.
