The 16-year-old Marist Brothers High School student broke two records in the sub-junior division at the Oceania Power Lifting Championship in Australia last Saturday.
Elder said the experience from the championship will certainly take him forward.
The fourth former set a new record in the squat lift with 222.5kg breaking the old record of 217.5kg.
He also set a new record in the dead lift with 237.5kg as the old record stood at 235kg.
