The husband of late Wellington lawyer Lecretia Seales has announced that a memorial lecture will be established in his wife's name.

The lecture - in partnership with Andrew Butler, lead counsel in Seales v Attorney General, and the Victoria University Law School - will be held annually for at least eight years and will be on the subject of law reform and the constitution of New Zealand.

Matt Vickers says former Prime Minister Sir Geoffrey Palmer QC has agreed to be the inaugural speaker, on 29 August 2016 at a venue to be confirmed.

The lecture will be held jointly with the launch of Mr Vickers' book, Lecretia's Choice.

Lecretia Seales took a case to the High Court in May 2015, seeking a judgment that would protect her doctor from prosecution should she consent to be assisted to die.

Ms Seales passed away a year ago, on 5 June 2015, on the same day the judgment in Seales v Attorney General was delivered. Though Ms Seales did not get the ruling she sought, her actions helped provoke a parliamentary inquiry into assisted dying which is currently underway.

Ms Seales was named New Zealander of the Year 2015 by The New Zealand Herald.
