As most of their debt is denominated in NZD, the best way of looking at their debt is in NZ dollars as follows:
Interest Bearing debt:
Convertible notes($A155mil)$NZ 195mil (due Dec 2012 to Mar 2014)
Capital leases $NZ 68mil (due over 5yrs but mainly 2011)
Project debt $NZ 20mil (due in 2009/10)
Operating leases $NZ 22mil (due over 5yrs)
TOTAL $NZ 305mil

Non-interest bearing payables:(all current)
Accounts payable $NZ 42mil
Less:Cash $NZ 17mil
Less:Accounts receivable $NZ 5mil
Capital committments $NZ 10mil
TOTAL $NZ 30mil

GRAND TOTAL $NZ 335mil

Again in 2011 they could have positive operating cashflow of around $NZ 300mil - so debt shouldn't be a problem.
