A New Zealand transgender lifter will go for gold against an American Olympic medallist when the super-heavyweight classes bring the weightlifting World Championships to a close on Tuesday.

Laurel Hubbard, 39, who competed nationally as Gavin Hubbard, has a perfect record since returning to competition after changing gender four years ago.

NZ transgender weightlifter Laurel Hubbard.

She has won the three events in which she has taken part, all in Australia, since her debut in international weightlifting last March and is in New Zealand's team for the Commonwealth Games on Australia's Gold Coast next April.

Based on the world rankings, Hubbard should be a gold-medal contender in the +90 kg class at the worlds where American hopes rest with Sarah Robles, from San Diego, who was third at the Rio Olympics last year.
