Hi Kathy
Regret to say that there is no newspaper for Te Aroha for c25 July 1901 held at National Library - regardless what the National Library Catalogue says:
'Aroha & Ohinemuri News and Upper Thames advocate' 1885-1917
1900-1907 <6814-6815>
The catalogue entry implies there is a complete run of papers from 1900-1907. In fact, the run is very patchy and there is only one issue held for 1901 - 5 dec.
The reference book you need - and I couldn't access it today as it had wandered off somewhere - is D R HARVEY's List of New Zealand newspaper holdings (c1987). He listed the newspapers by place and then paper title, then listed the holdings, not just libraries but also museums, historical societies, etc. Most good-sized libraries have a copy.
Best wishes
Elli
