Gross domestic product estimates the size of an economy by calculating the value of goods and services produced.
Nigeria is currently the fourth largest African economy, according to International Monetary Fund figures, after occupying top spot until 2022.
It has been replaced by South Africa, Egypt and Algeria.
Moses Waniko, a senior official at the National Bureau of Statistics (NBS), said the new exercise could show that Nigeria had a bigger economy than currently estimated.
