Motorists are being warned of delays on two Auckland motorways due to debris.
A left and centre lane under the Main Highway overbridge near Ellerslie had closed and drivers were being instructed to merge right.
Large shards of glass littered the road.
The New Zealand Transport Agency said just after 1pm that the area had been cleared and that all lanes were now open.
However, motorists were being warned: "Traffic remains very heavy from Hobson St onward travelling south.
"Please delay your journey if possible and expect delays as congestion slowly eases.''

At 1.30pm, a crash was reported on the State Highway 16 and SH1 interchange, northbound.
Authorities are working to clear debris from a lane just before the Victoria Park tunnel.
A photo from an NZTA camera shows what appears to be a mass of white powder streaking the lane.
Drivers are encouraged to drive slowly, avoid the area or expect delays.
