A 23,000 signature petition protesting against proposed tourist development work in Southland will be presented to Acting Prime Minister Bill English this morning.
South Island Company Riverstone Holdings is proposing a monorail as a shortcut for tourists travelling from Queenstown to Te Anau.
Similarly, tourism developers Milford Dart Ltd is suggesting a $160 million privately owned 11.3 kilometre tunnel behind Glenorchy.
But the Glenorchy-based Stop the Tunnel campaign and the Save Fiordland group say they are against the idea of a tunnel being built through conservation land.
Local residents say either option will destroy the peaceful nature of the region.
