The Titahi Bay Transmitter, which until 16 February 2016 was New Zealand's second tallest structure, transmitted AM radio signals from a 220 metres tall radio mast insulated against ground at Titahi Bay in New Zealand.{{Cite web|url=http://www.radionz.co.nz/national/programmes/mediawatch/archive/2004/20040201r|archiveurl=https://archive.today/20110518051933/http://www.radionz.co.nz/national/programmes/mediawatch/archive/2004/20040201r|archive-date=2011-05-18|url-status=dead|title=Radio New Zealand National : Programmes A-Z : Mediawatch : Archive : 2004 : 01 February, 2004 – The Titahi Transmitter}} The station which previously had three masts, now consists of only one mast with a height of 137 metres.{{Cite web|url=https://www.naturespic.com/NewZealand/image.asp?id=31226|title=Landmark 137 metre high radio mast at Whitireia Park, Titahi Bay, Titahi Bay, Porirua City District, Wellington Region, New Zealand (NZ).|website=Nature's Pic Images, New Zealand}} A third – smaller – mast with a height of 53 metres was toppled on 10 November 2015.

In 2004 the tower was refurnished, badly corroded parts were removed and replaced, the whole tower was sand-blasted and repainted, and an array of LED warning lights were added at the behest of the NZCAA.{{Citation needed|date=September 2023}}

According to workers refurbishing it, scaling the tower takes 45 minutes. From the top there are views of the entire Kapiti coast region.{{Citation needed|date=September 2023}}

The site formerly transmitted Radio New Zealand's shortwave service, these broadcasts used a series of shorter free-standing masts supporting curtain arrays.{{Citation needed|date=September 2023}}

Under the right conditions, the AM signal for National Radio can be received as far north as Norfolk Island and as far south as Dunedin.{{Citation needed|date=September 2023}}

The Department of Conservation owns the land surrounding the tower, which is leased to Radio NZ for the transmitting towers, to the local Titahi Golf Club, and as farm land. The site is located within Whitirea Park, and is planned to come under the control of the Greater Wellington Regional Council.{{Citation needed|date=September 2023}}

Only in recent years{{when|date=September 2014}} has the station's emergency power generator been replaced. The previous one, supplied by the American military after the Second World War, formed part of the driving machinery of a submarine which was no longer required.{{Citation needed|date=September 2023}}

The site was never used for overseas telephone links, which (before the advent of undersea cables and satellites) were provided by two New Zealand Post Office radio stations, Makara Radio (receiving) west of Wellington and Himatangi radio station (transmitting) near Himatangi Beach. Only a limited number of voice circuits were available, and overseas toll calls were expensive.{{Citation needed|date=September 2023}}
