Commuters are being advised to plan ahead and allow extra time as thousands of concert goers flock to Mt Smart Stadium.
Forsyth Barr Stadium is steadily filling up as Dunedin buzzes in anticipation ahead of the first of three Ed Sheeran concerts.
Support act Mitch James had taken to the stage by 6.45pm, with Six60 to perform next ahead of Sheeran taking to the stage after 8.30pm.
The hub in the Octagon was a sea of children and tiny instruments this afternoon as 1100 Otago school pupils from 42 schools exhibited their ukulele skills.

Food trucks are parked up and the outdoor areas of lower Octagon bars are packed and bustling.
Traffic was earlier backed up on the road from Christchurch to Dunedin as fans make their way south and the fencing had to be put up on Bath St as fans flocked to get pictures taken with the Sheeran mural.
By just after 1pm a line of 120 of hardcore Sheeran fans were waiting outside Forsyth Barr Stadium to ensure a good spot for tonight's concert and numbers had swelled further by 4pm.

The most hardcore, who started waiting last night, were attempting to get a bit of sleep early this afternoon after a night interrupted by rain.
Among them were , Annabelle(14) and Laura Ring (12), of Dunedin, among the about ten super fans who started waiting last night, who said they were confident of having a great night despite being tired.
Annabelle said she hoped "adrenaline" would kick in
Dany Musgrave (13), of Christchurch, lined up about 1pm after getting up about 6am with the rest of her family and being driven from Christchurch.
She was busy putting together a sign asking Sheeran if she could get up on stage and sing with him, which would fulfil a lifelong dream.
"I've always wanted to go on stage and sing with a famous singer," she said
More than 100,000 people have bought tickets for Ed Sheeran's three shows at Forsyth Barr Stadium over the next few days and the shows are expected to bring in $34 million to the local economy.

The singer touched down at Dunedin Airport in a private plane just after 7pm last evening and was quick to head to Bath St to see ''his'' mural.
The city has prepared for Sheeran's visit with extra emergency services, extra council services including transport, special events and beautified streets.
Senior Sergeant Mark Donaldson, of Dunedin, said extra police staff would patrol the stadium and Octagon areas, although he would not specify how many.
"Obviously a considerable amount, because it's one of the biggest events Dunedin has ever had, if not the biggest."
A '"considerable amount" of traffic was expected from Southland and Canterbury. In particular, commuters should expect "significant delays" in the city and on State Highway 1 north.
"Additional resources are being pushed on to our highways to make sure people are driving safe and to the conditions. We're also having to factor in people travelling over from Warbirds."
People should plan their journeys early in case of delays, he said.

Police had added significant extra resources for the weekend of Ed-mania, but Sheeran would not be getting a dedicated police escort.
St John coastal Otago territory manager Doug Third said an extra ambulance would be on the road during day and night shifts in preparation for the busy weekend.
St John was expecting a "marked increase" in callouts.
Twenty St John staff would also be working at each concert.
Fire and Emergency New Zealand East Otago area commander Laurence Voight said the service would have an extra vehicle dedicated to the concerts at or near the stadium.
Southern District Health Board acting operations general manager Joanne McLeod said extra staff would be on duty at the Dunedin Hospital emergency department over Easter.
"We want Dunedin residents and visitors to enjoy themselves, and our message is everything in moderation. Don't binge-drink, keep hydrated, be sensible in the sun and keep safe."

She advised people to "keep the emergency department for emergencies".
Dunedin Mayor Dave Cull said Sheeran's concerts were likely to create the single biggest inflow of money ''from essentially one event'' Dunedin had ever had.
"We're as ready as we'll ever be.
"What I can say is that I am aware of all the work the council and others have put in, including obviously stadium staff. I'm delighted that we've taken it as an opportunity to show what a great host Dunedin is."
A lot of work had gone on behind the scenes to ensure everything ran as smoothly as possible, and to make sure events were spread throughout the city, he said.
The Dunedin City Council is providing extra bins and waste collections to cater for the crowds.

Council community services general manager Simon Pickford said waste collection and street cleaning would be done each day around the Octagon, with crews available to respond if needed.
Three extra parking enforcement officers would be working tomorrow, Sunday and Monday to ensure people followed restrictions, particularly around mobility parks and loading zones.
The Lower Octagon and part of lower Stuart St have been closed to traffic to create the "Octagon Experience", which the council describes as a central hub for concert weekend activities and performances. It is filled with street furniture, plants and accent lighting.
Parking restrictions are in place around the stadium from 2pm to midnight each concert day to encourage people to "walk and use public transport to get around town".
Buskers and food stalls will be stationed along the walk down Stuart St to the Railway Station and along Anzac Ave to the stadium.
