Papua New Guinean sisters Thelma and Dika Toua each won gold medals at the Oceania Weightlifting Championships in New Caledonia.

Dika Toua, the elder of the sisters who also won silver at this year's Commonwealth Games in Gold Coast, triumphed in the under-53 kilograms division at the multi-purpose arena in Le Mont-Dore. 

She trailed Mary Kini Lifu of the Solomon Islands by 3kg after the snatch but fought back superbly in the clean and jerk to triumph by the slenderest of 1kg margins overall with 164kg.

Natalia Chorobczyk of Australia took a distant bronze with 150kg.

Thelma had earlier lifted a 150kg total to win gold in the under-48kg event.

She comfortably defeated Guam's Dayalani Reiko Vida Calma, second with 105kg, and Nauru's Carmen Deidenang, third with 80kg.

Fiji's delegation and eight athletes from New Zealand are absent from the continental-wide after the two teams failed to submit drug-testing whereabouts forms.

The few Fijian athletes still eligible are nonetheless not competing as they were suspended following a dispute within the body. 

New Zealand have still enjoyed plenty of success so far, however.

She lifted 194kg to beat Australia's Kylie Jane Lindbeck, second with 190kg, while another New Zealander in Zoe Glasson took third with 168kg.

Kiribati won two gold medals on the men's side.

Ruben Katoatau won the under-69kg event with 270kg to beat Nauru's Larko Doguape and Uea Detudamo, who were second and third with 248kg and 242kg.
