Firefighters from several Wairarapa towns joined forces when two cars collided north of Masterton only minutes after a large grass fire broke out in the town.
Wellington area Assistant Commander Nick Pyatt said about 20 firefighters from Masterton and Carterton had battled a blaze that erupted in tinder dry grass and underbrush on the banks of the Waingawa River near Hood Aerodrome about 4.30pm on Tuesday.
He said another fire crew from Greytown had been scrambled to a crash at Opaki on SH 2 north of Masterton less than 20 minutes later. Wairarapa rural firefighters were also on hand at the blaze.
He said the grass fire had scorched an area of more than 200sq m and involved five fire engines and crews who took about 45 minutes to contain the blaze using water drawn from the river.
"It was quite an effort at first to get a water source established but once we had that, we got on top of it pretty quickly and, in conditions like this, we need to make sure it's well and truly extinguished before we leave."
