There could be trouble on the outskirts of the leak saga for National Party President Peter Goodfellow.

Goodfellow hasn't confirmed or denied whether he knew about harassment complaints against Jami-Lee Ross as early as 2016.

Ross was kept on as an MP, and up until this week, was ranked seventh within the party.

The only complainant who's been named, Katrina Bungard, claims she was harassed to the point she sought medical treatment and the party's executive for help.

Pollster and party-aligned blogger, David Farrar, told Mike Hosking at least in her case, she was satisfied with their response.

"She actually said she's got no complaint about what the party did, she's absolutely traumatised by what happened, but she actually says she's happy with what Peter [Goodfellow] and Greg [Hamilton] did."
