Emergency services at the scene where Isaiah Oxley-Pirini, 2, was hit by a car in the Cowles Stadium car park.

Christchurch's basketball community is rallying around the family of a 2-year-old boy who died after being run over in a stadium car park.

The toddler was hit at Cowles Stadium in east Christchurch on Friday evening.

Emergency services were called to the Pages Rd stadium just before 5pm.

A police spokesman said the boy received medical attention but sadly died at the scene.

Extended family members are still being informed about the death. Police have not yet released the boy's name.

The Canterbury Basketball Association said on its Facebook page that all teams playing at Cowles Stadium this weekend would wear black tape on their arms in a show of support.

"We're very saddened about the terrible tragedy that occurred at Cowles Stadium [on Friday], and our condolences are with the family who have lost their child," the statement said.

A woman, believed to be the child's aunty, commented on the post, saying she was grateful for the support the association had shown.

Friends of the toddler's parents took to social media to send their love to the family in the aftermath of the "heartbreaking" incident.

At the scene on Friday evening, witnesses were visibly distressed and still being interviewed by police.

A cordon was established in place at the rear of the car park by the playground and snooker hall.

Police are investigating the circumstances of the boy's death.

Cowles Stadium is a facility run by the Christchurch City Council. It has multiple courts for hire and a wide range of school activities.
