Meridian's hydro storage levels have significantly decreased, with national storage dropping to 72% of the historical average for May.
In the South Island, storage is now at 73% of average, while the North Island's storage decreased to 64% of average.
The company also experienced lower inflows, as May's total inflows were only 45% of the historical average.
In addition, the Waiau catchment inflows were at 66% of average, and Meridian's Waitaki catchment water storage stood at 77% of average by the end of May.
These developments come amid New Zealand's coldest May in 15 years, which saw below-average rainfall in most of the South Island.
