The boss of SkyCity says the Sky Tower will continue to stand out, as Auckland's skyline evolves.

The iconic landmark is celebrating its 25th birthday today, marking the occasion with ticket discounts and family-friendly entertainment.

SkyCity COO Callum Mallett told Mike Hosking it still looks fantastic, even after all the debate around its construction.

He says public feedback, particularly around the lighting, is that it still looks current and he expects it'll continue to do so after another 25 or even 50 years.
