State Highway 34 (SH 34) is a New Zealand state highway in the Bay of Plenty region in the North Island.

It links the forestry town of Kawerau to Tauranga, Rotorua and Whakatāne.

It reaches SH 30 where it shares a short concurrency, turning left then immediately right.

SH 34 then travels south-west through the northern outskirts of Kawerau and past the Tasman Pulp and Paper Mill.

It continues westwards until it intersects SH 30 again and terminates.
