Organisers of the Wairarapa Water Summit in Masterton next week are fielding calls from throughout the country and overseas.
The summit, organised by the Wairarapa Regional Irrigation Trust, will be held on Tuesday at Copthorne Solway Park and will explore the economic and social opportunities of increased irrigation in Wairarapa and the challenges involved.
Trust chairman Bob Tosswill said so far the summit had attracted a range of interests from local and central government, and environmental, business and community interests throughout Wairarapa.
"We also have registrations from Australia and from Auckland, Canterbury, Hawke's Bay and Manawatu.
"The environmental and economic management of New Zealand's freshwater continues to be a hot topic, with the next stage of the Government's freshwater reforms announced just last week," Mr Tosswill said.
