Interpretation
Projects and Output Interpretation
New Zealand's construction industry is wrestling with a dual reality: it's simultaneously pouring billions into ambitious infrastructure and commercial projects while failing to build enough homes, leaving residential consents in retreat and completions lagging so far behind demand that the country is essentially constructing a magnificent new skeleton but forgetting to put enough flesh on the bones.
