Rotorua's popular Polynesian Spa is celebrating 50 years in business, but the famed thermal waters have been attracting visitors for centuries, writes Thomas Bywater.
Home to a huge range of tourist attractions, Rotorua is also the place where international visitors first experienced the region's manaakitanga - the extension of hospitality to strangers.
"We're the birthplace of tourism," says Gert Taljaard, chief executive of the Polynesian Spa.
The spa supposedly enters a sixth decade this year. However, a clear beginning of bathing at the pools is as mercurial and hard to pin down as volcanic mud.
It was on Easter weekend of 1972 when the business was renamed Polynesian Spa. It saw 2000 visitors on opening day but people had been enjoying the thermal waters long before that.
"We've been welcoming Europeans since at least 1878 when Father Mahoney came over from Tauranga," says Taljaard.
The rheumatic Catholic priest made the pilgrimage over the hills to "take the cure". The pumice Priest's Bath is named in his honour.
For tourists, the alkaline pools quickly became associated with wellness and a cure for a variety of Victorian ailments. Among the long list of treatments recorded by Rotorua Museum are cures for "plethora and corpulency", "congestions of the viscera" and "sexual impotence".
Although the ailments date the visits, the pools had been welcoming travellers for centuries.
