he or she may fix a later day as the last day of voting.
(2) If the election manager fixes a later day as the last day of voting, he or she must—
(a) immediately give public notice of the new last day of voting; and
(b) if postal ballot envelopes have not yet been issued, indicate in the notice the week in which they are likely to be issued.
