The Mackenzie District mayor says public toilets are being left in shambles from tourists driving through and feels let down by the government after it shelved the possibility of bed taxes.On Sunday the National Party ruled out the idea of a bed tax, promising that there will be "no new taxes" if it's re-elected.It comes after Prime Minister Christopher Luxon spoke publicly a fortnight ago about the possibility of three new taxes under National - a bed tax, a bank tax, and a fuel excise increase.Finance spokesperson Nicola Willis said policies like a bed tax would only hurt those booking weekends away and the party would instead look at existing mechanisms to help councils cope with tourism costs. She said the party would continue to invest in front-line services.But Mackenzie District mayor Scott Aronsen told Morning Report revenue from the taxes would not only have helped fund fixing and maintaining the region's creaking sewage system but also make improvements to public amenities."At least the bed tax should have some form of consistent income," he said."When we talk about IVL (International Visitor Conservation and Tourism Levy), we've really tried hard to get a share of that on an annual sort of a basis, but the reality is most of that money has gone to DOC (Department of Conservation) and we've missed out."The Auckland and Queenstown Lakes District mayors had also expressed their disappointment with National's announcementAronsen said some of the IVL funding was needed for basic operating costs, including cleaning toilets.He said that was especially the case in Tekapo, but Burkes Pass was overlooked."Now Burkes Pass is a little very small village between Tekapo and Fairlie and we've got one single public toilet on the side of the road there and it gets absolutely hammered," Aronsen said."We now have problems in the Burkes Pass service system, whereby it's running at capacity all the time now and we're getting those big pink stickers from ECan (Environment Canterbury) saying that you're exceeding your consent limits, you've got to do something about it."So that's just a real classic example, we take the eyes off Tekapo and look at Burkes Pass for instance."Aronsen said a bed tax would have allowed them to build it into their budgets.We would have some sort of idea based on bed nights every year, what we could derive from it, he said."But the problem with IVL is one minute you're in favour and the next you're not and then you've got to go begging with cap in hand to try and get some or you've got to be continually beating the drum," Aronsen said."If we had a bed tax at least we would know exactly what was more or less going to come in each year based on visitor numbers."Aronsen said they had been let down by the government."Well of course we are because we've been promised a loaf of bread and we've been given a rock, you know, that's the reality," he said."It's election year and politicians are doing what they do best and quite frankly we're pretty annoyed about it."If you're not going to give it to us, don't open your mouth in the first place. That's my message."
