Distance runner Zane Robertson has been added to the New Zealand team for next month's world championships in Moscow.
The 23-year-old, who is based in Kenya, qualified for the 5000m after recording a time of 13 minutes 13.83 seconds at a race in Belgium on Saturday, which bettered his personalbest by eight seconds and went under the A selection standard of 13:15.00 for the world championships.
Despite running the third fastest ever 5000m by a New Zealander at the weekend, Robertson is still considered a novice over the distance, having run only a handful of races over the distance. He came close to qualifying for the 1500m at last year's London Olympics, running 3:36.53.
Robertson will join his twin brother Jake, who was earlier named in the 10,000m. Having both represented New Zealand at the 2011 world cross country championships, the Hamilton twins will be the first siblings to represent New Zealand at a world and field championships.
The brothers are now in St Moritz, training under the eye of their coach Steve Willis who has previously guided his brother Nick at major championships.
