"Canterbury has been driving much of this, but there is emerging evidence of a broadening lift in hiring and investment in other regions too."
Westpac economist Michael Gordon said that because the survey did not directly cover the agricultural sector it might understate the impact of the drought and it also excluded the public sector, where spending caps were likely to be a sizeable drag on the pace of growth over the next couple of years.
But Eaqub said the survey included suppliers to the farm sector and firms which processed its output. Historically, droughts had not materially undermined the survey's reliability.
A net 4 per cent of firms reported an increase in staff numbers, from 3 per cent recording falls in the previous quarter.
Eaqub said that was consistent with 2 per cent annual growth in employment though inconsistent, he acknowledged, with other labour market indicators. Hiring intentions are also positive.
ANZ economist Mark Smith said: "While these results are encouraging, a sustained recovery in employment remains the missing link to a concerted economic expansion taking place. We still need to see expectations converted into reality."
The building sector returned the most positive numbers for output, employment and new orders, and a flattening off in the growth in its costs.
The survey presented a mixed picture of manufacturing. A net 5 per cent of firms reported an increase in staff numbers and a net 11 per cent reported higher exports, up from the last two quarters. But their selling prices are under pressure.
