Te Pāti Māori says its candidate Hana-Rāwhiti Maipi-Clarke's home has been invaded again, with an elderly Pakeha man issued a trespass notice.
Last Friday, Te Pāti Māori said in a statement the home of Maipi-Clarke, its Hauraki-Waikato candidate, was invaded and vandalised.
Now, Party president John Tamihere claims it has happened again.
He issued an explosive statement late last night, claiming the man behind Wednesday's incident was a "well-known" advocate and campaigner for the National Party.
"There should be no doubt now in anyone's mind that National and ACT's race baiting has empowered and emboldened a dangerous type of human being who is hell-bent on silencing Māori by targeting who they think is our most vulnerable," Tamihere said.
In response, a National spokesperson said "these were serious allegations" and police had not been in touch with the party.
"Te Pāti Māori's comments are the first time we were made aware of these allegations."
"National utterly rejects racism and any suggestion that we have engaged in race-baiting."
Tamihere claims police have failed and are not taking the matter of "politically motivated" attacks on Maipi-Clarke "seriously".
"The police have performed poorly by their failure to take these matters seriously and by refusing to investigate all incidents thoroughly. They could have taken criminal proceedings further by laying charges for unlawful entry knowing that Hana and her home has been a target. Instead, they chose not to," he said.
"We are left with no choice but to elevate this matter to the Commissioner."
Tamihere said if it was a Māori man unlawfully entering the home of a young Pakeha woman, it would be a "different story".
He says there's been a "string of attacks" on the candidate within the past week and he won't allow police to "treat us differently because we are brown".
"We will not allow for any of our mokopuna to be treated as a target and we will not allow the Police to dismiss us or treat us any differently because we are brown," Tamihere said.
"We will always be relentless in our fight for justice for our people and especially for our mokopuna."
ACT has hit back at Te Pāti Māori on Thursday morning, refuting its claims.
In the statement on Wednesday night, Te Pāti Māori said the home invasion was caused by "National and ACT's race-baiting", which "empowered and emboldened a dangerous type of human being who is hell-bent on silencing Māori by targeting who they think is our most vulnerable".
But ACT Party leader David Seymour said there is "zero evidence to support this claim" and he believes Te Pāti Māori shouldn't be taken "seriously" by media until they produce evidence.
"ACT condemns any acts of abuse or violence on the campaign trail but trying to stir up political division by baselessly accusing other party leaders of responsibility only makes things worse," Seymour said.
"Te Pāti Māori refuse to comment further because there's a police investigation but they still politicise it. This both excuses political violence by saying it's caused by someone else and risks justifying violence in retaliation."
It comes after a group of Māori and community leaders called for National leader Christopher Luxon to condemn "racist" comments by a New Zealand First candidate and "race-baiting" policies by the ACT Party - both of which are the Nats' prospective coalition partners.
ACT Party leader David Seymour denied any link between the language his candidates are using and the attack on Maipi-Clarke's home.
He told AM on Monday the comments by Te Pāti Māori are politicising the incident and could lead to "inciting further political violence".
Labour leader Chris Hipkins previously called for an end to "race-baiting and racist comments" on the election campaign.
Newshub has approached police for comment.
