The Manufacturers and Exporters Association found export sales jumped by 17 percent and domestic sales rose 8 percent.
The Association's current performance index, which combines profitability and cash flow, rose 6 points to 100.3. A reading above 100 indicates expansion.
However, the association says risks and pressures remain, including a high dollar and lower demand from Australia.
It also says the construction sector is reporting a shortage of tradespeople and labourers.
