Mrs Barr, her husband Rob and two daughters have been living in Burkina Faso and are back in New Zealand for a holiday.
Soroptimist International of Gore will host the event to celebrate women at the Gore Racecourse Food Affair Restaurant next Tuesday at 6.30pm.
Mrs Barr said life was very different in Burkina Faso to New Zealand.
"It can be particularly challenging for women and young girls."
