Whanau said on Instagram the mural is “a message of peace” and should not be removed.
“Yesterday, unfortunately, another mural calling for a Free Palestine was removed by council officers from the same spot.”
She said art helps people to “digest unimaginable harm and things that we may struggle to comprehend”.
“It can be confronting, uncomfortable, difficult, a call for peace or a stamp of the heartache of a city”.
She said murals should only be painted over if they incite hate or are inappropriate for children.
Whanau is the latest official to call for a ceasefire in Gaza which has been under fire from Israel since October 7, when Palestinian militant group Hamas orchestrated a series of coordinated attacks on bordering areas of Israel, killing more than 1200 people - mostly civilians.
Israel’s subsequent strikes of retaliation have killed more than 11,000 people - mostly children. The figure has surpassed the total amount of Palestinian deaths in the last 15 years of conflict with Israel and with more than 2000 people missing in Gaza it is likely to be higher.
The Israeli Defence Force has said it is carrying out a “precise and targeted operation against Hamas in a specified area” of Al-Shifa hospital in Gaza, claiming that Hamas is using civilians as “human shields”.
Human shields were “a key pillar of Hamas’s terror operations”, The Times of Israel quoted Israeli army spokesperson Daniel Hagari as saying. Israel has, however, not provided concrete proof for its allegations.
Israel also issued an order for 1.1 million Palestinians in Gaza City to flee to the south of Gaza within 24 hours - an impossible order to follow for many.
Once Palestinians did flee, Israeli forces targeted the safe route out of the city with airstrikes, killing at least 70 who were fleeing.
In October more than 800 scholars and law practitioners wrote a public statement calling what is happening in Gaza a genocide.
“We are compelled to sound the alarm about the possibility of the crime of genocide being perpetrated by Israeli forces against Palestinians in the Gaza Strip,” they wrote.
“We do not do so lightly, recognising the weight of this crime, but the gravity of the current situation demands it.”
Protests both for Palestine and for Israel have been attended by thousands globally, including in New Zealand.
* Correction: An earlier version of this article incorrectly stated that the Israeli military had defended using missile strikes against hospitals in Gaza. The military has said it has conducted a “precise and targeted” ground operation against Hamas in a specified area of Al-Shifa hospital in Gaza.
