Weather forecasts are being publicly funded on two fronts with both Niwa and Metservice now offering short range forecasts, using taxpayer funds to compete against each other.
The launch of Niwa's new short range service for farmers and growers puts it in a head-to-head battle with Metservice, while private forecasters fear the government forecasters' combined clout could heavy them out of the market.
Niwa is publicly funded as a Crown Research Institute and Metservice receives Ministry of Transport funding to provide free forecasting and severe weather warning services.
Metservice's Jacqui Bridges said there were differences between the services but customers were asking why publicly funded services were competing.
"We have had comments from people that they find it strange," Bridges said. "Metservice is a commercial service so we compete. If people want to compete with us they can compete with us and we are up for that."
