It happens just once every two years - the chance to see Porirua's artists in action, in their workshops and studios. The Friends of Pataka organise the Porirua Arts Trail, and this year around sixty have signed up. Alongside the many established artists and craftspeople in the area north of Wellington will be newcomers, including students from Whitireia Polytechnic. Lynn Freeman headed there to meet three expert artists in their fields. There's Moses Viliamu who's researching Tokelaun tattoos, and Kohai Grace who's with the Toi Poutama Weaving Collective. It also sees the return of multi- media artist, Michel Tuffery, who explained why he was so keen to get involved in the arts trail again. The Porirua Arts Trail takes place on March 13 and 14.
