Female politicians fear a normalised "toxic environment" of gendered abuse is stopping women from wanting a seat at the decision-making table.

Now, National Party deputy leader and Finance Minister Nicola Willis is calling for people to join her in "belittling the trolls" as she shares a message for an online harasser: "Stuff off".

Willis spoke at a gathering for women in local government, ahead of the LGNZ SuperLocal conference on Wednesday.

She announced the Ministry for Women is working with Netsafe on a toolkit for workplaces supporting women in leadership positions, including for local council candidates.

Willis says gendered harassment has become normalised, and provided examples of social media posts from anonymised accounts.

During the presentation, she had screenshots saved to a "folder of doom".

Willis read a "particularly spicy" one: "Eff up bitch, you ruin lives, that makes you an effing rhymes-with-munt."

She went on to say it was as though some believed her to be a "defective mother" for daring to be in such a public role.

"I share it with you to say it is real, we all get it."

It's this toxic virtual environment she believes poses a risk to women's participation in public roles.

The nature of online abuse means it's constant, easily spread and contributes to the normalisation of violence against women and girls, she says.

By sharing their experiences, women can know they are not alone.

"I encourage you to join me belittling the trolls.

"The impact of online abuse on female politicians is significant.

"And so we do need to allow better protection for women and find ways to make this kind of abuse socially unacceptable."

To her anonymous harasser, she saiys "Stuff off, you pathetic little troll".

Willis also spoke of New Zealand's "trailblazing" suffrage movement.

"I'm proud to be one of the seven women that sit around the Cabinet table, allowing us to advise on, decide and guide some of the most crucial decisions for our country."

Local body elections in 2022 saw the most women ever gain seats at council tables, with 45.5 percent of positions won by females.

Willis sees it as her job to not only acknowledge the good, but also the bad.

With the increase in representation of women, there's beginning to be a "disturbing trend of online violence against women and politics and other leadership positions".

Two mayors share their experiences

Tararua District Council mayor Tracey Collis has a method for dealing with abuse coming to her.

If it's a threat, she goes straight to the police.

All the other "ugly" communications goes to the chief executive.

As a recipient of unexpected house calls from ratepayers, Collis is a "big advocate" for not having full addresses visible to the public during elections.

Safety is top of mind.

Collis says there's a "genuine concern" people think twice before standing.

"It's just having an understanding of people's emotions and how they are sharing those but we need to keep ourselves safe ... it can take an emotional toll."

Rotorua mayor Tania Tapsell says it's fantastic connecting with other women in local government and hearing shared experiences.

It's also heartbreaking hearing how familiar they all are with dealing with harmful content, she says, especially on social media.

"It is deeply concerning that aspiring leaders are looking at what we're currently dealing with and are concerned that the toll it takes may not be worth it.

"The work we do to improve our communities is so important and we really can't let the level of hate and violence demonstrated be seen as acceptable or tolerated."

Tapsell sees it as not a woman's issue, but a New Zealand-wide issue.

"I encourage people to report abusive posts on social media."

Her own experiences include phone abuse and threats of violence.

"There are instances I've had to report issues to police and received support from Netsafe."

What she reported to police related to messages conveying if the senders saw her, they would hurt her, she says.

Referring to the Netsafe announcement, she said she was grateful the tools were available, and encouraged people facing abuse to reach out for support.
