Moonshine Rd (Upper Hutt side, not the hill road) is terrible for this.  Traffic on SH2 has just passed the 100kmh sign and is entering a corner when, invariably, someone will gently exit Moonshine Rd and accelerate glacially to around 50kmh to account for the 75kmh rated corner after the bridge.

That forces someone on SH2 to brake hard mid corner from generally between 80 and 100kmh.

There is zero merge lane as it's essentially a give way intersection with no ability to speed up before inserting yourself into the traffic flow.
