Lewis Tracing

I have been on this research for a long time and now I have made some progress in my search for Maata Te Tuku
but still need confirmation as finding records for her is hard. I know Maata Te tuku married Manapouri Lewis of Wairoa plus hear say that Maata Te Tuku is from Otorohanga Waikato, New Zealand and she has land there. Unsure as I cant find records on her name Maata Te tuku or Wharoa I think that's the spelling.
Is there anyone who knows or research her or seen a record and can put me on the site.

Cheers
