The pursuit of Olympic gold could see shot putter Val Adams call time on her season this week.
A decision is pending, but Adams' inability to throw beyond 19m in competition means a tilt at a fifth consecutive world championship on August 22 in Beijing is unlikely.
Attempting to become New Zealand's first Olympian to win a gold medal at three consecutive Games in Rio next year looks a more logical goal.
Among Kiwis, only Adams, runner Peter Snell, rowers Dick Joyce, Caroline and Georgina Evers-Swindell, coxswain Simon Dickie, kayakers Ian Ferguson and Paul MacDonald and equestrian rider Mark Todd have won golds at consecutive Olympics.
Adams has spent the season rebuilding after undergoing surgery to her right elbow and left shoulder last year.
