Reti ShaneDr SHANE RETI (National—Whangarei): I want to speak today about regional growth and how Whangarei is growing—the population is increasing—the new population economy and then a little bit on data. Whangarei is growing the economy is growing and a look at independent front-page newspaper headlines for any month will show this. Let us look at some of the front-page headlines for this month: Friday 3 March Wellingtonians move north for stable ground."; Saturday 4 March "State Highway 1 project will be biggest ever."; Monday 6 March "mayors optimistic about growth."; Thursday 16 March "Housing record $421500—our highest median price ever."; and just last Saturday 22 March "Chinese tourism surge on agenda." Independent organisations are also telling us Whangarei is growing and the economy is growing.In December last year Infometrics identified Marsden Point and One Tree Point as a future economic hub. Just last month the Maxim Institute identified Whangarei as one of seven areas close to Auckland with population growth through 2038 to 2043. Whangarei is growing and the new population brings a new economy. In the past 2 years Whangarei has probably grown by about 1000 households. Each household has an average weekly expenditure of $1000: housing transport energy food and accommodation. Over a year that is $52 million that has been cycled into the Whangarei economy through new population growth. Whangarei is growing.With growth comes a need for infrastructure and Whangarei is showing that infrastructure growth. There are new school buildings at Whangarei Girls' High School Pārua Bay School Kamo Intermediate School and Hora Hora Primary School. There is new roading—the Brynderwyns Kensington roundabout and the massive half-billion-dollar four-laning from Whangarei to Ruakākā roundabout. These are big roading projects that commuters see but there are also smaller projects that smaller communities really notice. Tikipunga Kauri and Kaurihohore School are very pleased with the proposed safety improvement to the hairpin bend on Saleyards Road just off State Highway 1 and we thank the New Zealand Transport Agency for this. The data is compelling: Whangarei is growing.In a more global and general sense it is data exploration that I want to briefly turn to. Over summer I read a fascinating article from the Smithsonian Institution looking at how data streams can be passed through a complex algorithm and turned into music. It actually passed 133 years of climate data through an algorithm and generated musical notes. I wondered what other data could be put through this so I went online to the TV3 poll data and pulled the party vote data for Labour and New Zealand First and I ran it through this algorithm and created two music clips.I listened closely to both of these clips and I did not immediately recognise the melodies so I played the clips through Shazam. Shazam is an application that recognises music and gives it a title. I was interested to know what titles it came up with. Unfortunately there was no match as both were fundamentally unintelligible and not of human origin. That was when I knew I was on to something. Not only was I mapping Labour and New Zealand First party vote data; I was also mapping their policies—unintelligible and not of human origin.But I was not finished. I thought there has got to be some interpretation and some value to take from this. So without prefix prelude or prior knowledge I sought the indulgence of an audience I was speaking to to play the clips and do a little bit of mood analysis with a five-point Likert scale. It went like this: I said to them "I want to play this short music clip. When I've finished I'll ask you to raise your hand across a five-point scale for what mood you associate—how does it make you feel?". It went from happy OK neutral anxious or scared. I played the two clips and people raised their hands and expressed how they felt. The Labour music data—well the room felt sort of neutral. It had no view either way and could take it or leave it—who cares. The music we played for New Zealand First data however had almost a complete majority in the room saying they felt scared.In conclusion is it not amazing how technology and a bit of applied science can so accurately describe the features of our Opposition colleagues—neutral and scary. With that I leave the technology and corroboration of these findings in the hands of the House and the voters."
