The Ponsonby Rd ANZ branch is home to one of four GayTMs in the country - ATM machines transformed by the bank with vibrant colours and rhinestones.
They were first introduced by ANZ Australia last year to celebrate the Sydney Mardi Gras and were commissioned in New Zealand as part of the bank's diversity programme, with the proceeds from the use of non-ANZ customer cards being donated to OUTline, a not-for-profit counselling service that supports people dealing with gender and sexuality issues.

This was not the first time the Ponsonby Rd GayTM was targeted - it was covered in white paint over the weekend in what many believed was a homophobic attack.
However, in a blog post, an anonymous group calling themselves Queers Against Injustice said they targeted the GayTM to draw attention to the commercialisation of the Pride Festival, which also took place over the weekend.

A note left at the Ponsonby Rd ANZ branch last night said "pinkwashing" was a term used to describe how the LGBTQIA struggle was "co-opted to whitewash over unethical behaviour".
"We see in in Aotearoa when corporations (such as ANZ) strategically use gay-friendly marketing to increase profits by exploiting their workers' rights," the note said.
The note also made mention of an incident at last weekend's Pride Parade in Auckland, where a woman was allegedly injured during an altercation with security.
"A Maori transwoman was tackled by a security guard, her arm broken, and she was refused medical attention by police for 25 minutes while she was protesting the inclusion of a police float in the parade."
This morning a spokesman from ANZ said it was too early to say whether last night's attack was carried out by the same group.
He said most of the paint was cleaned up while it was still wet.
