Direct equipment inputs as a share of the cost of New Zealand heavy and civil construction, 2020

What it is. 10.1% of the total inputs of the heavy and civil construction industry: direct equipment inputs (consumption of capital 3.8%, maintenance of equipment 2.1%, equipment hire 1.7%, all other equipment 2.5%).

Sample. Statistics New Zealand's 2020 input-output tables for the heavy and civil construction industry, as tabulated by Te Waihanga. Diesel, 1.7% of the same total, is recorded as its own finding. The denominator is the industry's total inputs including taxes, subsidies and margins (8.0%).

What it is not. Context only: how large equipment is in the industry's cost structure, not a share lost or overspent: the source does not measure plant hours against what was priced. A whole-industry cost structure for one year, not a contract's. Includes consumption of capital (depreciation), which a hire-rate or utilisation overrun would not move. Diesel burned by subcontractors sits in the services inputs, not here.
