That resulted in a loss of about $5.3 million for impairment, reflecting a decline in the assets' fair value.
Dunedin Railways had forecast ongoing losses and a need for more equity and its board was preparing a turnaround plan when the forecast effects of Covid-19 on the tourism sector made the challenge of carrying on too difficult.
The company was put into hibernation as an alternative to closure.
Train trips have since been run on a trial basis to test whether a domestic market could be established.
DCHL's debt was also forced up.
Total term loans were almost $24.5million at June 30, 2020, or $3.5million higher than budget.
This was because of increased investment in Dunedin Railways, allowing the company to repay its debts.
The effect of Covid-19 also resulted in lower-than-expected dividend income from City Forests.
The actual dividend was $4.5million against a budgeted $6.5million.
This is expected to be recovered in the 2021 financial year.
Delta Utility Services' dividend was $1.5million, as expected.
Aurora Energy did not produce a dividend, as expected.
