Hosted by Dunedin, New Zealand, Lobb participated in a number of events and returned with two gold and two bronze medals.
He won gold in the M65 long jump (3.76m) and M65 triple jump (7.55m), and placed third in the M65 pentathlon (combined event with long jump, javelin, 200m, discus and 1500m).
He was also part of a composite relay team that featured two Tahitians and one British athlete, which finished a close third in the M240+ 4x100m relay.
The annual general meeting of Oceania Masters Athletics (OMA) was held on the rest day during the championships, and Lobb was re-elected as the vice president of OMA.
The meeting also confirmed the hosts and dates of the next two championships.
These are set to be held in Mackay, North Queensland, from August 31 to September 7 in 2019, while the 2021 Champs will be held on Norfolk Island in late January 2021.
