The owner of the farm that has denied access to the site of the proposed Ruataniwha Catchment Proposal dam strongly denies Labour leader David Cunliffe's inference that he is part of a conspiracy.
Mr Cunliffe had unsuccessfully applied to visit the dam site last week, as had expert witnesses for the board of inquiry's public hearing of the proposal.
"If someone visits tomorrow I have to knock off docking and drop hot wires [electric fences] - it's like Fort Knox," Mr Preston said.
"For people to infer I am somehow part of a conspiracy to block people out of this place incenses me.
"I know it looks bad because of the eighth [final inquiry submission date] but the reason I set the 10th was I would have finished docking and be through the first cycle of my calving - it would be down to one hot wire to get out there."
