Tributes are flowing for cyclist Melissa Desley Rays, who died in a crash in east Auckland.

Rays, 58, was critically injured on Marua Rd in Mt Wellington just before 8am on Monday and was rushed to hospital. She died later that day.

Police are continuing their investigation into the crash.

"Police extend their sympathies to her friends and family."

Rays was a Mt Wellington resident, police said.

Rays' friend Jackie Taylor-Fox said she lost her "beautiful best friend and soul sister in a tragic accident".

"I can't believe she has been taken but I know we truly loved each other so much and we always had the best times through the almost 40 years of our close friendship," Taylor-Fox said.

"And we had so much more to do together too."

Witnesses told the Herald police examined a white van that had broken glass and damage to the driver's side of the vehicle, and a person in the van spoke with officers.

The vehicle was reportedly towed from the scene.

Loved ones and fellow cyclists have paid respects and left floral tributes at the corner where Rays was found.

Staff at a nearby lunch bar feared the cyclist was one of their regulars because she always wore a pink helmet and would stop in every morning for a hot chocolate – a routine they said she has kept for at least six years. 

The worker told the Herald the woman would normally arrive between 7.50am and 8.15am, always with a smile on her face. 

Monday's crash was reported at 7.54am. 

Other nearby workers said drivers travel "too fast" around the "tricky" corner where the crash occurred, and often travel into the flush median. 

They said the crash was "very distressing".
