"Shakti is organising a vigil to honour Xi Wang and to draw attention to domestic violence in this country," said a spokeswoman.
"This vigil is to honour her life, to mourn her death and to join together to say 'enough' to domestic violence."
Rotorua farmer Ephraim Beazley has been charged with murdering Wang.
He will appear again in the High Court at Auckland next month.
The couple met when Wang was travelling and studying in New Zealand.
She decided to stay and marry him. However they separated while she was pregnant with their first child.
Wang's death came soon after the alleged murder of British backpacker Grace Millane.
Vigils were held for Millane across New Zealand - but as little information was able to be shared about Wang, nothing public was held directly in her honour.
Shakti hoped to do just that on January 30.
They said it was also important to spread the message about violence towards women.
"We need to take domestic violence just as seriously as gender-based violence perpetrated by strangers such," they said.
"While we grieve and mourn for Xi Wang, we hope and pray for the day when all women can live lives free from fear and violence.
"We hope and pray when migrant women of colour who face additional barriers to seeking help and accessing justice can receive just as much support, compassion and understanding from the general public."
New Zealand has one of the worst rates of domestic violence in the developed world.
Shakti said that female immigrants and refugees often had their experience, voices and deaths "marginalised".
"We witness the violence and the effects of domestic violence every day and the struggles in accessing justice, especially when the perpetrators are Pākehā men," Shakti's spokeswoman said.
"We invite you to join together to honour Xi Wang, to honour all the women whose lives had been taken at the hands of men.
"Her death is a reminder to us all of the brutality and fatality of domestic violence in Aotearoa.
"We all need to do better."
