NZVRS Library <<<back to NZVRS homepage

The NZVRS maintains a fairly extensive collection of radio related material under the tender care of the NZVRS Librarian, Ernie Hakanson. However the library is always on the lookout for any radio related circuit information - especially early New Zealand manufactured items.

Circuit information from the library collection is available to members at a minimal copy fee. It is possibly best to communicate with Ernie first to get a quote on the cost and availability of the information sought before sending your request and cheque. All cheques should be crossed "Not Transferable" and made out to the NZVRS.

The NZVRS Librarian's contact details are;

Sorry due to Ernie’s sudden death the NZVRS Library will remain closed until the end of April 2008.

All correspondence should be forwarded to the main contact for the NZVRS or email: office@nzvrs.pl.net;

PO Box 13873, Onehunga, Auckland 1643, NZ
