Up to 100 Wellington bus commuters have reportedly been left stranded amid a chaotic morning described by one driver as the worst he has seen in more than 20 years.

The problems were reported in the Wellington suburbs of Hataitai and Kilbirnie on Tuesday morning.

My bus driver tells me today is the worst he's seen in 23 years on the job in Wellington.



Metlink are 10-15 drivers short and sometimes 10-15 buses are broken. Today could be both. — Ben Strang (@BenJStrang) May 14, 2018

One commuter said up to 100 people were waiting at bus stops at 8.30am after some services were cancelled and another four were too full to pick up passengers.

The problem was also evident on Monday night, when some commuters were left stranded in the rain as Miramar, Hataitai and Lyall Bay buses were at capacity.

"Hundreds of angry commuters were stranded at stops in Wellington this morning with some refusing to pay for unexplained cancellations and totally under par bus services halting morning commute and school transportation," the commuter said.

"What is happening when commuters are being stranded in peak hour?"

Another commuter experienced similar problems.

"This morning I waited 30 minutes for a bus from Hataitai to town, from 8.02am to 8.32am.

"During that time three full buses went past without stopping and, according to the RTI [real-time information board], another two buses were cancelled.

"The bus that finally did stop could only take about four of us, so we left about 10 people at my stop, about eight at the next stop and 30 or 40 at Hataitai village."

The problems had been occurring for over a month, the commuter said.

One bus driver told a commuter the chaos was the worst he had seen in his 23 years as a bus driver.

Metlink was 10 to 15 drivers short and another 10 to 15 buses appeared to be broken, he said.

In response to a separate complaint from one of the commuters a week ago, Metlink apologised and said it was disappointed by the disrupted services.

"​Unfortunately, Go Wellington [NZ Bus] has recently experienced a shortage of bus and driver availability which has resulted in a number of services in the city to either be cancelled, or the services that do run to reach capacity early in the route.

"This is a current issue that we are aware of and we will be running as many serviced buses as possible in each area of the city during peak hours."

The city's bus network will be completely overhauled from July, when new bus routes and contracts come into effect.

It is hoped the new network will solve recent capacity issues across the city and make the service more accessible.
