"The Serious Crash Unit is in attendance and will examine the scene," police said.
"An investigation into the circumstances of the crash will commence in due course."
The cyclist, 19-year-old Levi James, died at the scene.
James was hit on Manukau Rd near the Royal Oak roundabout - a stretch of road that has been subject to safety concerns and analysis for many years, with suggestions not enough has been done to keep road users, especially cyclists, safe.
He was remembered as a kind-hearted son who loved to support his school's rugby team and rebuild old motorcycles with his dad.
"It's the most devastating thing ever, I could never have imagined what it would have been like, and now that we're in the middle of it there's nothing worse," his mother, Kim James, said.
