Elsewhere in New Zealand police have been asked to visit Trans-Pacific Partnership (TPP) activists and find out their plans for February 4, when the agreement is signed in Auckland.
Whanganui's most vocal speaker on the issue, Denise Lockett, has not had such a visit.
"They haven't knocked on my door. How disappointing," she said.
But she wouldn't be surprised if her phone was monitored and said large numbers of TPPA Action Whanganui group emails were unexpectedly undeliverable at certain times.
"Sometimes half of them come back. That was very strange."
