October's output growth was above the 3.3 percent annual rise forecast in a Reuters poll, and was up from the 2.3 percent expansion in September.

The index measures output from the manufacturing, electricity generation and mining sectors.

Growth was supported by an increase in all indexes tracked, led by a 5.4 percent annual rise in the manufacturing sector, data from the Department of Statistics showed.

The electricity sector index grew 2.1 percent from a year earlier while mining expanded 1.4 percent, snapping a five-month streak of declining growth.

Malaysia's exports surged in October, rising 17.7 percent from a year earlier, amid strong demand from China and higher shipments of manufactured and mining goods.
