She said rent reviews were done annually in line with the consumers price index but management did work with individual retailers to take into account their circumstances.
The Herald understands existing food-court tenants pay a $13,000 monthly base fee, and retailers pay $10,000 for an 80sq m retail shop.
One tenant asked why they didn't just reduce the rates for current tenants. "How can they do this? They come to us and say the lease is ending, I want you to go."
She said it was hard for owners who invested between $200,000 and $400,000 in buying their businesses to relocate.
Another said it was heartbreaking to be putting in 12-hour days, seven days a week only to be forced out.
A retailer wrote to the Herald raising concerns about how Westfield was behaving and said it had "no regard for local people and the small businesses that locals run to support their families" as it continued to impose annual rent rises in tough times.
"We have had our lives torn at the seams due to Westfield's unrelenting greed and an attitude that is completely out of sync within a tough Hamilton retail market."
