The Meteorological Service, the state-owned weather bureau, reported a 5.6 per cent drop in annual profit as a bigger tax bill and higher costs from its new acquisition muted earnings.
Profit fell to $2.6 million in the year to June 30, from $2.7 million a year earlier, according to Wellington-based MetService's annual report.
Sales rose 7.9 per cent to $45.6 million, its third-highest since becoming a state-owned enterprise in 1992. Profit before tax increased 13 per cent to $4.3 million.
In the financial year, the company spent $3 million on a 49 per cent stake in MetOcean Solutions, a New Zealand-based oceanographic business, to further its international commercial subsidiary MetraWeather, which provides weather content in a variety of mediums around the globe.
During the year it formalised its "weather as a service" unit and expanded its digital output, providing an online content, graphics and clips site for media outlets.
