Ms Fletcher would not make any comment about measures which would be taken to ensure last year's reported high levels of intoxication were not repeated.
Masterton police senior sergeant Carolyn Watson said police would have a significantly increased presence at this year's event in order to monitor intoxication levels and vendors' licence compliance. Police would be meeting Toast Martinborough ticket holders off buses and trains and at the gates to check for anyone who had being drinking before the event.
"We're not there to stop people from having fun, we're there to stop that small minority who spoil other people's fun."
She said police would not be heavy handed and would not be routinely breathalysing festival-goers, but relying on observation.
"It's pretty obvious when somebody has preloaded, slurring and stumbling, especially at that time of the morning."
Ms Watson said it was a well-run event and that police were there to support organisers.
