Carvings - A Pair

I spotted these two carvings marking the entrance to a complex on Ferry Road in Christchurch. I've been trying to establish exactly what the complex is and it appears to be a Maori cultural centre of some sort. I'll be bringing you photographs of the stunning little whare (meeting house) I saw there, in a few days time - and hopefully a bit of the history behind it. I always think it's a pity that there are so many Maori carvings and buildings around the country with absolutely no indication at all as to their origins or current uses. Where they obviously arouse interest, perhaps local councils could consider putting up a small plaque or an information board. That wouldn't break the bank, surely?
