I don't have any data on the Reptile One bulbs so I can't comment on their effectiveness one way or another. It's looking to be difficult to find T5 bulbs on the sites I've searched over there. I did find an Arcadia T8 but it's a little smaller than the fixture you have now. It may be worth inquiring about different size options available. http://www.animates.co.nz/reptile/reptile-heating-lighting/arcadia-reptile-light-15w-18in.html
It looks like there are several bricks and mortar stores across the North Island and a couple on the South (Christchurch and Nelson) so you may be able to save shipping costs if you're near one as well.
PS It's amusing me to respond to a post from New Zealand because I'm watching Paul Henry's morning show online as I write this =)
I'm not across the moat , but Arcadia gear is darned hard to find here too (in Australia) and I'm fed up with being overcharged for rubbish chinese clones by sellers here so I bought my Arcadia MVBs from a place in the USA and had them shipped to me by USPS airparcel post (I bought 4 of the 80W MVBs , essentially got the 4th one for nix which covered the postage).
I bought from LightYourReptiles.com
I'm sure you can do the same with their UV tubes as well.
(And yes they are made for 240V 50Hz so work fine here).
If LightYourReptiles will ship internationally for reasonable cost, it's a good option. I use them as well. Very high quality stuff and easy to work with.
Unfortunately it looks like they don't ship to New Zealand. How much does it cost to get shipped to Australia? I'll email him and ask if he can ship to NZ specially but I don't have high hopes. Thanks anyway though! Maybe I can get my cousins to forward it from aussie all the other reptile sites I found in the US cost around $80 NZD to get shipped here which is ridiculous since thats the price of the tube
Edit: looks like their tubes are only 22" instead of 24" ? Based on that alone maybe i shouldn't spend a whole bunch of money only to have it not fit, unless its a typo

I have a bearded dragon arriving in 2 weeks, and am in the process of getting an enclosure set up ready for it. The choice of UVB options available here sure is limited!
So sorry about the late reply!!
I ended up sticking with the Reptile One uvb bulb, as i havent had any issues with it in the past year of using these bulbs. My beardie hasn't been ill at all since i got her as a baby
Good luck!!
