Four Aucklanders are heading to China for the IAAF Athletics World Championships in August. Valerie Adams (shot put), Portia Bing (heptathlon), Michael Cochrane (hurdles) and Jacko Gill (shot put) will be part of the New Zealand team heading to the Birds Nest in Beijing. Cochrane received an IAAF invitation to compete in the world champs by winning his events at the Oceania Championships in Cairns. He was nominated on the basis that he has the potential of a top 16 placing at the Rio Olympic Games. The final selection for the world champs will be made on August 11.
