JamesL: Nice, when I was in Greytown over labour weekend the 3G was seriously slow! (on Spark)

In the general Wairarapa Area Spark have activated new 4G 700mhz in Featherston, Martinborough, Greytown, Carterton (700mhz and 2600mhz on Carterton Central) and the new site on the Wairarapa Hospital Grounds (Lansdowne, Masterton) during the past few weeks. 

Vodafone has pretty good 4G in Wairarapa too other than Martinborough.
