KiwiRail, the state-owned rail and freight operator, widened its loss in 2018 with further writedowns to its rail network, even as revenue and underlying earnings gained.
The Auckland-based state-owned enterprise reported a net loss of $235.9 million in the year to June 30 versus a loss of $197.3m in the prior year.
That reflected an impairment charge of $248.6m on KiwiRail's rail assets, down from $295.8m.
As the rail network does not generate sufficient cash to cover the level of required investment, a large proportion of the accounting value must be written off each year, it said.
Earnings before depreciation, amortisation, interest, impairment, capital grants and fair value changes fell 7.1 per cent to $48.5m, weighed down by a $45m hit from the Kaikoura earthquake. Stripping out the quake impact, underlying earnings rose 2 per cent to $94m, while operating revenue gained 3.5 per cent to $615.8m.
