The area where the crash happened, between Kokiri St and Western Rd, has a 50km/h speed limit.
Mr Membery said the road was closed until about 8.30am while police carried out scene investigations.
Christine Roberts, employee at Express Bakehouse, said it took a long time for traffic to clear.
"They redirected traffic up Western Rd and it backed all the way to past the Gull. It's only just cleared now [8.45am], I started work about 6am so that would make it about two hours.
"I thought it was a truck crash... I saw the truck crashed into the pole, I didn't see it actually happen, but I saw it sitting there with its hazard lights on. And I didn't know a bike was involved until one of the customers came in a told me."
