Number of new entrants

Intake of new entrants peaked in 2007 for the construction industry. After the global financial crisis in 2009, intakes fell to half their pre-crisis levels. Since 2009 the construction industry has seen a steady growth in new entrants.

On the other hand the dairy farming sector saw growth in new entrants into 2008, however fell over the 2008/2009 season when dairy payouts fell. A similar shock is seen in the 2014/15 season when dairy payouts fell again.

New entrants are defined as workers first starting work in a given sector. We limit our new entrants to those working a full time equivalent for at least three months. This is done in an attempt to remove casual workers who have no intention of remaining in the workforce. Workforce numbers found in IRD records are often higher than other sources due to the inability to separate the workforce from its support and administration services.

Sectors within industries can be investigated by expanding the selector on the right (▶).

A new entrant is classified as an individual who first starts working (earning income in IRD records) within a given sector (defined through employer ANZSIC 2006 codes). We take new entrants in the sectors we follow between the years of 2007 and 2017.

Within IRD data there is no available information on the number of hours worked, only income at a monthly level. Because of this, we only consider an employee to be employed in a given month if they earn more than the equivalent of 0.5 FTE (80 hours) on the minimum wage. Thus for 2007 (minimum wage of $11.25) only months with income over $900 count as employed.

The food and fibre sectors are facing a growing shortage of workers. The solution may not lie with secondary school graduates.
