Anti corruption police investigating Papua New Guinea's National Statistical Office have reportedly been unable to find the acting national statistician.

Teenage pregnancy has fallen at an astonishing rate in recent years, "dropped like a stone", said one surprised national statistician.

Papua New Guinea's national statistician says he obtained two court orders at the end of last month to stay a warrant for his arrest.

Earlier, the UK National Statistician Ian Diamond also cautioned against relying on rankings.

Anti corruption watchdog Transparency International is calling on Papua New Guinea's government to suspend the National Statistician Roko Koloma.

According to Mr Mandea, the Acting National Statistician directed the termination of casual contracts initiated under his predecessor Roko Koloma.

Michael Kumung, the acting Registrar-General of the PNG Civil and Identity Registry, will be acting National Statistician for the next three months.
