The Reserve Bank has paid its biggest dividend in three years after its bottom line was boosted by the weaker Kiwi dollar.
The central bank paid $430 million as a dividend to the government in September, its third biggest, and up from $145m a year earlier.
The RBNZ reaped a $237m gain on foreign exchange revaluations in the year ended June 30, compared to a loss of $66m in 2017. That gain underpinned an almost trebling of the central bank's annual surplus to $456m from $155m, the bank's annual report shows.
A new dividend policy introduced for the Reserve Bank in 2009 allows the distribution to include foreign exchange movements if there is an expectation gains will be crystallised.
The finance minister makes the call with advice from the RBNZ's board and audit committee, among others.
